| Realm | uv |
| Authority | hl7 |
| Description | R4B: `ResearchStudy.objective` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `ResearchStudy.objective` as defined in FHIR R4B in FHIR STU3. The source element is defined as: `ResearchStudy.objective` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R4B: `ResearchStudy.objective` 0..* `BackboneElement` * R4: `ResearchStudy.objective` 0..* `BackboneElement` Following are the generation technical comments: Element `ResearchStudy.objective` has a context of ResearchStudy based on following the parent source element upwards and mapping to `ResearchStudy`. Element `ResearchStudy.objective` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
