[IDM.OCM.W-STACK.00036] Presentation Status
The Credential Manager MUST provide a way for a component to subscribe/unsubscribe for Presentation event updates when new Presentations are received or the status changes. A list of subscribers for a specific connectionID MUST be in place and maintained based on the respective implementation. This functionality of publishing events SHOULD be provided via a REST service, but a message bus system can also be considered.
