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