DescriptionR5: `ImagingSelection.instance` (new:BackboneElement)
PurposeThis extension is part of the cross-version definitions generated to enable use of the element `ImagingSelection.instance` as defined in FHIR R5 in FHIR R4. The source element is defined as: `ImagingSelection.instance` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R5 `ImagingSelection.instance` 0..* `BackboneElement` Following are the generation technical comments: Element `ImagingSelection.instance` is not mapped to FHIR R4, since FHIR R5 `ImagingSelection` is not mapped. Element `ImagingSelection.instance` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).
