Re: Existing missmatch between SDP mux and BUNDLE

I much prefer use of the term "media description" as well since this is 
well-defined in 4566.

Having said that, I wholeheartedly agree with Christer's point about 
terminology change - we need people to agree to this before entertaining 
yet another update on this front.

So folks, please speak up and let us know if you are for, against, or 
indifferent in terms of said terminology change.

Thanks
