| Title | R4: General specifications for this substance, including how it is related to other substances (new) |
| Realm | uv |
| Authority | hl7 |
| Description | R4: `SubstanceSpecification.property` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the
element `SubstanceSpecification.property` as defined in FHIR R4
in FHIR STU3.
The source element is defined as:
`SubstanceSpecification.property` 0..* `BackboneElement`
Following are the generation technical comments:
Element `SubstanceSpecification.property` is not mapped to FHIR STU3, since FHIR R4 `SubstanceSpecification` is not mapped.
Element `SubstanceSpecification.property` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
