The current approach is a compromise between between sending everything and sending a minimal message. (e.g., just the Encounter ) in which all Receivers would need to query back for more information. Will continue with this approach and review feedback from implementers on whether more or less data is needed for the use case. Also based on Da Vinci Guidelines Document: (see attached) "The requester should limit the request for information to that required to address the specific, stated purpose" . Therefore providing the minimum necessary to: provide enough information to understand what the notification is about and to enable the Recipient to determine if and what additional steps they need to take in response to the notification.
