Assuming A registers contacts A1, A2. When a network entity initiates a notification I am not sure if there is a possibility that it indicates different attributes (say rejected for A1 and probation for A2) for the individual contacts A1 & A2.
If the device register the same expires value for A1 and A2 and intends to keep them both registered with appropriate refreshes I don't see why the server would need to indicate different states for those contacts ever. Any use cases?

So any given notification will show all the contacts that are present at that time. So, if A registers, then B, then C, and then B unregisters, you should see notifications that contain: A, A+B, A+B+C, A+C.
