| Title | R4B: The source value set that contains the concepts that are being mapped (new) |
| Realm | uv |
| Authority | hl7 |
| Description | R4B: `ConceptMap.source[x]` (new:canonical(ValueSet), uri) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the
element `ConceptMap.source[x]` as defined in FHIR R4B
in FHIR R5.
The source element is defined as:
`ConceptMap.source[x]` 0..1 `canonical(http://hl7.org/fhir/StructureDefinition/ValueSet), uri`
Following are the generation technical comments:
Element `ConceptMap.source[x]` has a context of ConceptMap based on following the parent source element upwards and mapping to `ConceptMap`.
Element `ConceptMap.source[x]` has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element). |
