Aiee! This seems like crazy over-generalisation to me. Every different
content description markup will have its own way of describing what it
wants to do (if necessary), especially when we do stuff like re-using
existing namespaces like file transfer.

Why would you you want to say in two places you're doing audio, or say
in one place you're doing audio, and somewhere else say you're doing it
over RTP? Not to mention it would invoke yet another registry of
namespaces/values/attributes we have to take care of.

I was thinking of a direct analogy to the media field saying "audio" or
"video" in your m-line in SDP. So like:

  <content name="asdf">
    <description xmlns="...rtp" media="audio">

Then we'd just define some features to explain what media you supported,
