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