Registrtion of MIME media type audio/aptX

[Colin Perkins]

Greg,

We have previously discussed bringing this work to the IETF AVT  
working group. I would strongly suggest that you do so, submitting an  
Internet-Draft for your RTP Payload Format, and allowing the working  
group to provide advice. As they stand, these draft registrations  
fail to address the issues (correct media parameters, SDP,  
conformance to RFC 4855, etc.) in a number of ways.
