Subject: [MMUSIC] New Liaison Statement, "LS on Missing IANA Registration Information on SDP Attributes in RFC 2326"

MMUSIC,

We have received a liaison statement from 3GPP regarding missing SDP 
attributes at the IANA registry (see the e-mail below for details).

As the statement says:
> SA4 has identified that IANA registrations of three SDP attributes defined in RFC 2326, namely ‘control’, ‘range’ and ‘etag’, are missing

As a solution, the RTSP 2.0 draft already registers 'control' and 
'range' for RFC 2326 and RFC 2326bis 
(http://tools.ietf.org/html/draft-ietf-mmusic-rfc2326bis-34#section-22.15). 
However, in RFC2326bis 'etag' is renamed into 'mtag'.

Hence, it seems that we should also register 'etag' but for that 
reference RTSP 1.0 (RFC 2326) only.

Please review the liaison statement and our proposed solution and send 
your comments to us and to the list.

Thanks,
Ari & Flemming
(MMUSIC co-chairs)
