| Title | R4: definition additional types |
| Realm | uv |
| Authority | hl7 |
| Description | R4: `PlanDefinition.action.definition[x]` additional types (canonical(http://hl7.org/fhir/StructureDefinition/ActivityDefinition), canonical(http://hl7.org/fhir/StructureDefinition/PlanDefinition), canonical(http://hl7.org/fhir/StructureDefinition/Questionnaire), uri) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `PlanDefinition.action.definition[x]` as defined in FHIR R4 in FHIR STU3. The source element is defined as: `PlanDefinition.action.definition[x]` 0..1 `canonical(http://hl7.org/fhir/StructureDefinition/ActivityDefinition,http://hl7.org/fhir/StructureDefinition/PlanDefinition,http://hl7.org/fhir/StructureDefinition/Questionnaire), uri` Following are the generation technical comments: Element `PlanDefinition.action.definition[x]` is mapped to FHIR STU3 element `PlanDefinition.action.definition` as `SourceIsBroaderThanTarget`. The mappings for `PlanDefinition.action.definition[x]` do not cover the following types: canonical, uri. |
