This has been > reviewed in the IETF but is not the product of an IETF Working Group. > o Individual Submissions (NONE): SDP attribute for qualifying Media > Formats with Generic Parameters > <draft-rajeshkumar-mmusic-gpmd-03.txt> > Proposed Standard This looks to me like a substantive duplication of the media features facility defined in RFC 2533 and elaborated on in RFCs 2506, 2530, 2534, 2738, 2912, 2913, 2938, and 2987. Not only does this set of documents provide a full-featured media feature tagging and content negotiation facility, the relationship to MIME media types and parameters has also been worked out. Although the media features facility defined in these various RFCs is perhaps too elaborate for SDP's needs, it should at least be possible to reuse the basic descriptive elements of media features and the corresponding media features registry. At a minimum this draft needs to explain why the existing media features facility is unsuitable for SDP's use and another, similar facility needs to be defined. Ned
