The minutes of the IETF 84 does not show a lengthy discussion.  The 
message about the WG decision from the WG Chairs says "I support this".

I reordered the above paragraph as it is related to the comment I 
made above.  It is mentioned about that the authors believe that RFC 
4856 is the correct type.  There isn't any explanation about why the 
authors think so.  I do not see any response to my previous comment ( 
http://www.ietf.org/mail-archive/web/mmusic/current/msg12778.html ).

In my opinion, reading the corresponding codec specification is 
required to understand what the draft proposes.
