R5: ActivityDefinition.subject[x] additional types (canonical(http://hl7.org/fhir/StructureDefinition/EvidenceVariable))

This extension is part of the cross-version definitions generated to enable use of the element ActivityDefinition.subject[x] as defined in FHIR R5 in FHIR R4.

The source element is defined as: ActivityDefinition.subject[x] 0..1 canonical(http://hl7.org/fhir/StructureDefinition/EvidenceVariable), CodeableConcept, Reference(http://hl7.org/fhir/StructureDefinition/Group,http://hl7.org/fhir/StructureDefinition/MedicinalProductDefinition,http://hl7.org/fhir/StructureDefinition/SubstanceDefinition,http://hl7.org/fhir/StructureDefinition/AdministrableProductDefinition,http://hl7.org/fhir/StructureDefinition/ManufacturedItemDefinition,http://hl7.org/fhir/StructureDefinition/PackagedProductDefinition)

Across FHIR versions, the element set has been mapped as:

• R5: ActivityDefinition.subject[x] 0..1 canonical(http://hl7.org/fhir/StructureDefinition/EvidenceVariable), CodeableConcept, Reference(http://hl7.org/fhir/StructureDefinition/Group,http://hl7.org/fhir/StructureDefinition/MedicinalProductDefinition,http://hl7.org/fhir/StructureDefinition/SubstanceDefinition,http://hl7.org/fhir/StructureDefinition/AdministrableProductDefinition,http://hl7.org/fhir/StructureDefinition/ManufacturedItemDefinition,http://hl7.org/fhir/StructureDefinition/PackagedProductDefinition)
• R4B: ActivityDefinition.subject[x] 0..1 canonical, CodeableConcept, Reference(http://hl7.org/fhir/StructureDefinition/Group)
• R4: ActivityDefinition.subject[x] 0..1 CodeableConcept, Reference(http://hl7.org/fhir/StructureDefinition/Group)

Following are the generation technical comments: Element ActivityDefinition.subject[x] is mapped to FHIR R4 element ActivityDefinition.subject[x] as SourceIsBroaderThanTarget. The mappings for ActivityDefinition.subject[x] do not cover the following types: canonical. The target context ActivityDefinition.subject[x] is a choice-type element and cannot directly hold extensions. The context is moved up to parent element ActivityDefinition. The standard extension alternate-reference has been mapped as PART of the representation of FHIR R5 element ActivityDefinition.subject[x] with unmapped reference targets: AdministrableProductDefinition, ManufacturedItemDefinition, MedicinalProductDefinition, PackagedProductDefinition, SubstanceDefinition. Source element ActivityDefinition.subject[x] has unmapped reference types. While the target element ActivityDefinition.subject[x] is a choice type and does not allow extensions, the alternate-reference extension can be applied to Reference values within it.
