R5: Observation.value[x] additional types (Attachment, Reference(http://hl7.org/fhir/StructureDefinition/MolecularSequence))

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

The source element is defined as: Observation.value[x] 0..1 Attachment, boolean, CodeableConcept, dateTime, integer, Period, Quantity, Range, Ratio, Reference(http://hl7.org/fhir/StructureDefinition/MolecularSequence), SampledData, string, time

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

• R5: Observation.value[x] 0..1 Attachment, boolean, CodeableConcept, dateTime, integer, Period, Quantity, Range, Ratio, Reference(http://hl7.org/fhir/StructureDefinition/MolecularSequence), SampledData, string, time
• R4B: Observation.value[x] 0..1 boolean, CodeableConcept, dateTime, integer, Period, Quantity, Range, Ratio, SampledData, string, time
• R4: Observation.value[x] 0..1 boolean, CodeableConcept, dateTime, integer, Period, Quantity, Range, Ratio, SampledData, string, time

Following are the generation technical comments: Element Observation.value[x] is mapped to FHIR R4 element Observation.value[x] as SourceIsBroaderThanTarget. The mappings for Observation.value[x] do not cover the following types: Attachment, Reference. The target context Observation.value[x] is a choice-type element and cannot directly hold extensions. The context is moved up to parent element Observation.
