| Realm | uv |
| Authority | hl7 |
| Description | R4: `MedicationKnowledge.packaging` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `MedicationKnowledge.packaging` as defined in FHIR R4 in FHIR STU3. The source element is defined as: `MedicationKnowledge.packaging` 0..1 `BackboneElement` Following are the generation technical comments: Element `MedicationKnowledge.packaging` is not mapped to FHIR STU3, since FHIR R4 `MedicationKnowledge` is not mapped. Element `MedicationKnowledge.packaging` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
