Das DiseaseInformationHBVD-Profil ist eine Spezialisierung des DiseaseInformation-Profils.

Der Hauptunterschied zum Elternprofil liegt in der Bindung des questionnaire-Elementes an einen fest definierten Wert, der den zugrundeliegenden Fragebogen referenziert. In diesem Fall handelt es sich um die Questionnaire-Ressource DiseaseQuestionsHBVD. Diese Ressource wird neben der hier vorgestellten StructureDefinition für die Validierung der jeweiligen QuestionnaireResponse herangezogen. Dort werden auch die (fachlichen) Inhalte detailliert dargestellt, welche über die hier profilierte QuestionnaireResponse transportiert werden können/müssen.

DiseaseInformationHBVD (QuestionnaireResponse)	I		DiseaseInformation	There are no (further) constraints on this element Element id QuestionnaireResponse Short description A structured set of questions and their answers Alternate names Form, QuestionnaireAnswers Definition A structured set of questions and their answers. The questions are ordered and grouped into coherent subsets, corresponding to the structure of the grouping of the questionnaire being responded to. Comments The QuestionnaireResponse contains enough information about the questions asked and their organization that it can be interpreted somewhat independently from the Questionnaire it is based on. I.e. You don't need access to the Questionnaire in order to extract basic information from a QuestionnaireResponse. Data type DiseaseInformation Constraints dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources `contained.contained.empty()` dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated `contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()` dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource `contained.where((('#'+id in (%resource.descendants().reference \| %resource.descendants().as(canonical) \| %resource.descendants().as(uri) \| %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()` dom-6: A resource should have narrative for robust management text.`div`.exists() dom-5: If a resource is contained in another resource, it SHALL NOT have a security label `contained.meta.security.empty()` noItemText: Für alle Items ist das text-Element (item.text) nicht erlaubt. `repeat(item).all(text.count()=0)` Mappings rim: Entity. Role, or Act workflow: Event rim: Observation[moodCode=EVN]
id	Σ	0..1	string	There are no (further) constraints on this element Element id QuestionnaireResponse.id Short description Logical id of this artifact Definition The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. Comments The only time that a resource does not have an id is when it is being submitted to the server using a create operation. Data type string
meta	Σ	0..1	Meta	There are no (further) constraints on this element Element id QuestionnaireResponse.meta Short description Metadata about the resource Definition The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource. Data type Meta Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
implicitRules	Σ ?!	0..1	uri	There are no (further) constraints on this element Element id QuestionnaireResponse.implicitRules Short description A set of rules under which this content was created Definition A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. Comments Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
language		0..1	codeBinding	There are no (further) constraints on this element Element id QuestionnaireResponse.language Short description Language of the resource content Definition The base language in which the resource is written. Comments Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). Data type code Binding A human language. CommonLanguages (preferred) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
text		0..1	Narrative	There are no (further) constraints on this element Element id QuestionnaireResponse.text Short description Text summary of the resource, for human interpretation Alternate names narrative, html, xhtml, display Definition A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. Comments Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. Data type Narrative Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A rim: Act.text?
contained		0..*	Resource	There are no (further) constraints on this element Element id QuestionnaireResponse.contained Short description Contained, inline Resources Alternate names inline resources, anonymous resources, contained resources Definition These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope. Comments This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels. Data type Resource Mappings rim: Entity. Role, or Act rim: N/A
extension	I	0..*	Extension	There are no (further) constraints on this element Element id QuestionnaireResponse.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
modifierExtension	?! I	0..*	Extension	There are no (further) constraints on this element Element id QuestionnaireResponse.modifierExtension Short description Extensions that cannot be ignored Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). Requirements Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

basedOn	Σ I	0..0	Reference(CarePlan \| ServiceRequest)	There are no (further) constraints on this element Element id QuestionnaireResponse.basedOn Short description Request fulfilled by this QuestionnaireResponse Alternate names order Definition The order, proposal or plan that is fulfilled in whole or in part by this QuestionnaireResponse. For example, a ServiceRequest seeking an intake assessment or a decision support recommendation to assess for post-partum depression. Requirements Supports traceability of responsibility for the action and allows linkage of an action to the recommendations acted upon. Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Data type Reference(CarePlan \| ServiceRequest) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.basedOn rim: .outboundRelationship[typeCode=FLFS].target
partOf	Σ I	0..0	Reference(Observation \| Procedure)	There are no (further) constraints on this element Element id QuestionnaireResponse.partOf Short description Part of this action Definition A procedure or observation that this questionnaire was performed as part of the execution of. For example, the surgery a checklist was executed as part of. Comments Composition of questionnaire responses will be handled by the parent questionnaire having answers that reference the child questionnaire. For relationships to referrals, and other types of requests, use basedOn. Data type Reference(Observation \| Procedure) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.partOf rim: .inboundRelationship[typeCode=COMP].source[moodCode=EVN]
questionnaire	S Σ	1..1	canonical(Questionnaire)Fixed Value	Element id QuestionnaireResponse.questionnaire Short description Form being answered Alternate names Form Definition The Questionnaire that defines and organizes the questions for which answers are being provided. Requirements Needed to allow editing of the questionnaire response in a manner that enforces the constraints of the original form. Comments If a QuestionnaireResponse references a Questionnaire, then the QuestionnaireResponse structure must be consistent with the Questionnaire (i.e. questions must be organized into the same groups, nested questions must still be nested, etc.).

status	Σ ?!	1..1	codeBinding	There are no (further) constraints on this element Element id QuestionnaireResponse.status Short description Status der Fragebogeninhalte Definition Status der Fragebogeninhalte Requirements The information on Questionnaire resources may possibly be gathered during multiple sessions and altered after considered being finished. Comments This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. Data type code Binding Lifecycle status of the questionnaire response. QuestionnaireResponseStatus (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Event.status w5: FiveWs.status rim: .statusCode (also whether there's a revisionControlAct - and possibly mood to distinguish "in-progress" from "published)
subject	S Σ I	1..1	Reference(NotifiedPerson)	There are no (further) constraints on this element Element id QuestionnaireResponse.subject Short description Verweis auf die in der Meldung benannte betroffene Person. Alternate names Patient, Focus Definition Verweis auf die in der Meldung benannte betroffene Person. Hierbei handelt es sich grundsätzlich um den Verweis auf die in der Erregernachweismeldung als „subject“ referenzierte Patient Ressource. Requirements Allows linking the answers to the individual the answers describe. May also affect access control. Comments If the Questionnaire declared a subjectType, the resource pointed to by this element must be an instance of one of the listed types. Data type Reference(NotifiedPerson) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.subject w5: FiveWs.subject[x] rim: .participation[typeCode=SBJ].role w5: FiveWs.subject
id		0..1	string	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.id Short description Unique id for inter-element referencing Definition Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. Data type string Mappings rim: n/a
extension	I	0..*	Extension	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
reference	S Σ I	1..1	string	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.reference Short description Literal reference, Relative, internal or absolute URL Definition A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Comments Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
type	Σ	0..1	uriBinding	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.type Short description Type the reference refers to (e.g. "Patient") Definition The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). Comments This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. Data type uri Binding Aa resource (or, for logical models, the URI of the logical model). ResourceType (extensible) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
identifier	Σ	0..1	Identifier	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any). Data type Identifier Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: CX / EI (occasionally, more often EI maps to a resource id or a URL) rim: II - The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs.

display	Σ	0..1	string	There are no (further) constraints on this element Element id QuestionnaireResponse.subject.display Short description Text alternative for the resource Definition Plain text narrative that identifies the resource in addition to the resource reference. Comments This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
encounter	Σ I	0..0	Reference(Encounter)	There are no (further) constraints on this element Element id QuestionnaireResponse.encounter Short description Encounter created as part of Definition The Encounter during which this questionnaire response was created or to which the creation of this record is tightly associated. Requirements Provides context for the information that was captured. May also affect access control. Comments This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. A questionnaire that was initiated during an encounter but not fully completed during the encounter would still generally be associated with the encounter. Data type Reference(Encounter) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.encounter w5: FiveWs.context rim: .inboundRelationship(typeCode=COMP].source[classCode<=PCPR, moodCode=EVN]
authored	Σ	0..0	dateTime	There are no (further) constraints on this element Element id QuestionnaireResponse.authored Short description Date the answers were gathered Alternate names Date Created, Date published, Date Issued, Date updated Definition The date and/or time that this set of answers were last changed. Requirements Clinicians need to be able to check the date that the information in the questionnaire was collected, to derive the context of the answers. Comments May be different from the lastUpdateTime of the resource itself, because that reflects when the data was known to the server, not when the data was captured. This element is optional to allow for systems that might not know the value, however it SHOULD be populated if possible. Data type dateTime Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Event.occurrence[x] w5: FiveWs.recorded rim: .participation[typeCode=AUT].time

Requirements Need to know who interpreted the subject's answers to the questions in the questionnaire, and selected the appropriate options for answers. Comments Mapping a subject's answers to multiple choice options and determining what to put in the textual answer is a matter of interpretation. Authoring by device would indicate that some portion of the questionnaire had been auto-populated. Data type Reference(Device \| Practitioner \| PractitionerRole \| Patient \| RelatedPerson \| Organization) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.performer w5: FiveWs.author rim: .participation[typeCode=AUT].role

item	S I	1..*	BackboneElement	There are no (further) constraints on this element Element id QuestionnaireResponse.item Short description Groups and questions Definition A group or question item from the original questionnaire for which answers are provided. Comments Groups cannot have answers and therefore must nest directly within item. When dealing with questions, nesting must occur within each answer because some questions may have multiple answers (and the nesting occurs for each answer). Data type BackboneElement Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` qrs-1: Nested item can't be beneath both item and answer `(answer.exists() and item.exists()).not()` Mappings rim: n/a rim: .outboundRelationship[typeCode=COMP].target[classCode=OBS, moodCode=EVN]

Requirements A common pattern is to define a set of data elements, and then build multiple different questionnaires for different circumstances to gather the data. This element provides traceability to the common definition. Comments The ElementDefinition must be in a StructureDefinition, and must have a fragment identifier that identifies the specific data element by its id (Element.id).

extension	I	0..*	Extension	There are no (further) constraints on this element Element id QuestionnaireResponse.item.answer.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
modifierExtension	Σ ?! I	0..*	Extension	There are no (further) constraints on this element Element id QuestionnaireResponse.item.answer.modifierExtension Short description Extensions that cannot be ignored even if unrecognized Alternate names extensions, user content, modifiers Definition May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). Requirements Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

value[x]		0..1		There are no (further) constraints on this element Element id QuestionnaireResponse.item.answer.value[x] Short description Single-valued answer to the question Definition The answer (or one of the answers) provided by the respondent to the question. Requirements Ability to retain a single-valued answer to a question. Comments More complex structures (Attachment, Resource and Quantity) will typically be limited to electronic forms that can expose an appropriate user interface to capture the components and enforce the constraints of a complex data type. Additional complex types can be introduced through extensions. Must match the datatype specified by Questionnaire.item.type in the corresponding Questionnaire.
