| Description | R5: `Device.property` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `Device.property` as defined in FHIR R5 in FHIR STU3. The source element is defined as: `Device.property` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R5: `Device.property` 0..* `BackboneElement` * R4B: `Device.property` 0..* `BackboneElement` * R4: `Device.property` 0..* `BackboneElement` Following are the generation technical comments: Element `Device.property` has a context of Device based on following the parent source element upwards and mapping to `Device`. Element `Device.property` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
