| Realm | uv |
| Authority | hl7 |
| Description | R4: `ImplementationGuide.fhirVersion` additional types (code) additional types from child elements (value) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `ImplementationGuide.fhirVersion` as defined in FHIR R4 in FHIR STU3. The source element is defined as: `ImplementationGuide.fhirVersion` 1..* `code` Following are the generation technical comments: Element `ImplementationGuide.fhirVersion` is mapped to FHIR STU3 element `ImplementationGuide.fhirVersion` as `SourceIsBroaderThanTarget`. The mappings for `ImplementationGuide.fhirVersion` do not cover the following types: code. The mappings for `ImplementationGuide.fhirVersion` do not cover the following types based on type expansion: value. |
