Well, using my outline of deliverables [1], there will probably be a
basic way for Web User Agents to Discover web based Partner Providers
(§1-B), but it doesn't have to be the only mechanism.

This is absolutely the case (§1-C).

Right, this is certainly my hope (that people in the e.g. UPnP space
provide this).

Correct (§1-C/D)

Sorry, it does provide *a* mechanism for Discovery of /some/ services,
but the point is that it wasn't going to limit that to the only one,
and that other ways to be Discovered could be provided.

This should have been covered in the DAP minutes [2]. But it seems
that since I was tossing around the example, not everything that I
said was scribed and so it must have gone past people.

The point was that UAs could provide other mechanisms for adding
intents, and extensions could add intents, and vendors could
prepopulate intents, etc.
