DescriptionR4B: `ImplementationGuide.definition.page` (new:BackboneElement)
PurposeThis extension is part of the cross-version definitions generated to enable use of the element `ImplementationGuide.definition.page` as defined in FHIR R4B in FHIR STU3. The source element is defined as: `ImplementationGuide.definition.page` 0..1 `BackboneElement` Across FHIR versions, the element set has been mapped as: * R4B: `ImplementationGuide.definition.page` 0..1 `BackboneElement` * R4: `ImplementationGuide.definition.page` 0..1 `BackboneElement` Following are the generation technical comments: Element `ImplementationGuide.definition.page` is part of an existing definition because parent element `ImplementationGuide.definition` requires a cross-version extension. Element `ImplementationGuide.definition.page` has a context of ImplementationGuide based on following the parent source element upwards and mapping to `ImplementationGuide`. Element `ImplementationGuide.definition.page` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). Creating extension because element `ImplementationGuide.definition.page` is a content reference and requires an extesion definition.
