| Description | R4B: `NamingSystem.uniqueId.type` additional codes |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `NamingSystem.uniqueId.type` as defined in FHIR R4B in FHIR R5. The source element is defined as: `NamingSystem.uniqueId.type` 1..1 `code` Following are the generation technical comments: Element `NamingSystem.uniqueId.type` is mapped to FHIR R5 element `NamingSystem.uniqueId.type` as `RelatedTo`. The mappings for `NamingSystem.uniqueId.type` do not allow expression of the necessary codes, per the bindings on the source and target. |
