| Realm | uv |
| Authority | hl7 |
| Description | R5: `ObservationDefinition.category` (new:CodeableConcept) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `ObservationDefinition.category` as defined in FHIR R5 in FHIR STU3. The source element is defined as: `ObservationDefinition.category` 0..* `CodeableConcept` Across FHIR versions, the element set has been mapped as: * R5: `ObservationDefinition.category` 0..* `CodeableConcept` Following are the generation technical comments: Element `ObservationDefinition.category` is not mapped to FHIR STU3, since FHIR R5 `ObservationDefinition` is not mapped. Element `ObservationDefinition.category` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
