DSTU2: CommunicationRequest.payload.content[x] additional types (Attachment)

This extension is part of the cross-version definitions generated to enable use of the element CommunicationRequest.payload.content[x] as defined in FHIR DSTU2 in FHIR R4.

The source element is defined as: CommunicationRequest.payload.content[x] 1..1 Attachment, Reference(http://hl7.org/fhir/StructureDefinition/Resource), string

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

• DSTU2: CommunicationRequest.payload.content[x] 1..1 Attachment, Reference(http://hl7.org/fhir/StructureDefinition/Resource), string
• STU3: CommunicationRequest.payload.content[x] 1..1 Attachment, Reference(http://hl7.org/fhir/StructureDefinition/Resource), string
• R4: CommunicationRequest.payload.content[x] 1..1 Attachment, Reference(http://hl7.org/fhir/StructureDefinition/Resource), string

Following are the generation technical comments: Element CommunicationRequest.payload.content[x] is mapped to FHIR R4 element CommunicationRequest.payload.content[x] as SourceIsBroaderThanTarget. The mappings for CommunicationRequest.payload.content[x] do not cover the following types: Attachment. The target context CommunicationRequest.payload.content[x] is a choice-type element and cannot directly hold extensions. The context is moved up to parent element CommunicationRequest.payload. The standard extension alternate-reference has been mapped as PART of the representation of FHIR DSTU2 element CommunicationRequest.payload.content[x] with unmapped reference targets: Resource. Source element CommunicationRequest.payload.content[x] has unmapped reference types. While the target element CommunicationRequest.payload.content[x] is a choice type and does not allow extensions, the alternate-reference extension can be applied to Reference values within it.
