DescriptionR4B: `ExampleScenario.actor` (new:BackboneElement)
PurposeThis extension is part of the cross-version definitions generated to enable use of the element `ExampleScenario.actor` as defined in FHIR R4B in FHIR STU3. The source element is defined as: `ExampleScenario.actor` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R4B: `ExampleScenario.actor` 0..* `BackboneElement` Following are the generation technical comments: Element `ExampleScenario.actor` is not mapped to FHIR STU3, since FHIR R4B `ExampleScenario` is not mapped. Element `ExampleScenario.actor` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
