Make sure you also inline the first conf in the sdp...

I'm reading rfc3984 to pick parameters and parameters name in a way that
matches other rfcs, if you could have a look too and tell me which
parameters could be useful in your fields, I'll try to avoid ones that
don't make sense. The O/A section seems interesting too.

Let me know, hopefully I'll commit an update soon.
