Following up on this old thread:

First of all, I think we need to add a bit more text on the bundle/mux 
point for extensions in 4566bis.

Secondly, at IETF90, we also discussed (and concluded) that extensions 
should also state if they have any source-specific behavior [RFC5576] 
(see 
http://www.ietf.org/proceedings/90/minutes/minutes-90-mmusic#h.c5g3wcovj2qp). 
As far as I know, we didn't change this point at IETF91, but the minutes 
are silent on it, so I wanted to check what people think here again.

Thanks

-- Flemming
