DSTU2: StructureDefinition.constrainedType additional types (code) additional types from child elements (value) additional codes
This extension is part of the cross-version definitions generated to enable use of the
element StructureDefinition.constrainedType as defined in FHIR DSTU2
in FHIR R4B.
The source element is defined as:
StructureDefinition.constrainedType 0..1 code
Across FHIR versions, the element set has been mapped as:
StructureDefinition.constrainedType 0..1 codeStructureDefinition.type 1..1 codeStructureDefinition.type 1..1 uriStructureDefinition.type 1..1 uriFollowing are the generation technical comments:
Element StructureDefinition.constrainedType is mapped to FHIR R4B element StructureDefinition.type as RelatedTo.
The mappings for StructureDefinition.constrainedType do not cover the following types: code.
The mappings for StructureDefinition.constrainedType do not cover the following types based on type expansion: value.
The mappings for StructureDefinition.constrainedType do not allow expression of the necessary codes, per the bindings on the source and target.
Context of Use
This extension may be used on the following element(s)
StructureDefinition.type
This extension is allowed for use with FHIR versions R4B to R4B .
