R5: EvidenceVariable.characteristic.definitionCanonical (new:canonical(EvidenceVariable,Evidence))
This extension is part of the cross-version definitions generated to enable use of the
element EvidenceVariable.characteristic.definitionCanonical as defined in FHIR R5
in FHIR R4B.
The source element is defined as:
EvidenceVariable.characteristic.definitionCanonical 0..1 canonical(http://hl7.org/fhir/StructureDefinition/EvidenceVariable,http://hl7.org/fhir/StructureDefinition/Evidence)
Following are the generation technical comments:
Element EvidenceVariable.characteristic.definitionCanonical has a context of EvidenceVariable.characteristic based on following the parent source element upwards and mapping to EvidenceVariable.
Element EvidenceVariable.characteristic.definitionCanonical has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).
Context of Use
This extension may be used on the following element(s)
EvidenceVariable.characteristic
This extension is allowed for use with FHIR versions R4B to R4B .
