Good point. I would say the server responds to both the it can. The 
server cannot really know why the client is interested in a specific 
PVD. The server might have a good idea why the relay asks for some PVD. 
At the end the client is responsible handling the config information 
from all PVDs it receives, solicited or unsolicited.

Will do.

Agree with the solution approach. The client might be aware of more PVDs 
that is requests at some specific time. Whether the client then finds 
the unsolicited PVD information useful is another thing.
