Joerg,

Adding a semantic description to a media line is something I feel has
been missing in SDP, and it is something we can put to good use right
away.

I support it becoming a WG document - as the scope is much wider than of
the XCON/conferencing work. 

Short comment to the draft itself:
Limiting the scope of the semantics themselves by real world "use cases"
would be preferable. Interoperability wise it is much to gain by having
some semantics understood by most - than a lot of semantics understood
by few.
