Each mode only contains ONE value. This is what should be understood
from the draft.

I find it easier to have several "mode=X;mode=Y" rather than a "mode=X|Y".

What only question is about the meaning of "mode=X;mode=Y" -> It's usefull
for SDP usage (some speex implementation will support only mode X and Y), 
For media type registration? I don't know what could be the meaning: I'm
only a SDP offer/answer user and have no knowledge on media type use.
