This draft is basically ready for publication, but has nits that should 
be fixed before publication.

I noticed one nit (typo) in section 7:

    s/ecn-capaable-rtp/ecn-capable-rtp/

Beyond that I have one question/suggestion that I'm happy to have you 
consider or ignore as you see fit:

In the case of missing packets it seems that you have the opportunity to 
save some space by encoding a run of contiguous missing packets as a 
single packet metric block with L=0, using the remaining bits in the 
metric block to encode the number of missing packets. Whether that is an 
optimization worth the trouble to do is a question I can't answer.

Otherwise, IMO this draft is ready to go.
