| Title | R4B: Properties by which a Subscription can filter notifications from the SubscriptionTopic (new) |
| Realm | uv |
| Authority | hl7 |
| Description | R4B: `SubscriptionTopic.canFilterBy` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `SubscriptionTopic.canFilterBy` as defined in FHIR R4B in FHIR R4. The source element is defined as: `SubscriptionTopic.canFilterBy` 0..* `BackboneElement` Following are the generation technical comments: Element `SubscriptionTopic.canFilterBy` is not mapped to FHIR R4, since FHIR R4B `SubscriptionTopic` is not mapped. Element `SubscriptionTopic.canFilterBy` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). |
