I agree that we can't make anything mandatory to implement that we don't 
have an accepted stable, publicly available reference for. (I'm working 
on solving that for the case of VP8).

However, I don't agree that we necessarily have to complete a standards 
process in order to refer to it; that would put, for instance, the Zip 
format (used, among other places, in OOXML and ODF) out of scope for 
standards.

WRT IPR issues: I think we just have to push forward on the assumption 
that all IPR holders who are part of the process will do their duty and 
disclose any relevant IPR, and hope that IPR held by nonparticipants in 
the process is not serious enough to cause us to regret our decision.

Note: The statement about VP8 in the rtcweb-protocols document is a 
placeholder, put in there to indicate that we need to have the 
discussion. It's not a WG decision, but input to a WG discussion.
