| Title | R5: Detailed information about any events relevant to this notification (new) |
| Realm | uv |
| Authority | hl7 |
| Description | R5: `SubscriptionStatus.notificationEvent` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the
element `SubscriptionStatus.notificationEvent` as defined in FHIR R5
in FHIR R4.
The source element is defined as:
`SubscriptionStatus.notificationEvent` 0..* `BackboneElement`
Across FHIR versions, the element set has been mapped as:
* R5: `SubscriptionStatus.notificationEvent` 0..* `BackboneElement`
Following are the generation technical comments:
Element `SubscriptionStatus.notificationEvent` is not mapped to FHIR R4, since FHIR R5 `SubscriptionStatus` is not mapped.
Element `SubscriptionStatus.notificationEvent` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). |
