I know many of you had hoped you'd next see SDP as an RFC, but a few minor points cropped up at last call to do with internationalisation and character sets that required fixing. Thanks to Steve Hanna for pointing these out before they became more difficult to fix. A new draft is available from: ftp://ftp.isi.edu/confctrl/docs/draft-ietf-mmusic-sdp-05.txt ftp://ftp.isi.edu/confctrl/docs/draft-ietf-mmusic-sdp-05.ps This won't appear in the internet drafts archives until after the December IETF as I missed the deadline. The changes clarify the use of ISO 10646 in SDP where the wording was ambiguous, and the requirements on alternative character sets that may be specified. A few minor changes were also required to the spec: - The BNF for attribute values was too restrictive. This was an error; even some of the attributes described in the spec couldn't be represented! It now allows the full UTF-8 encoded charset to be used for attribute-values. - Some attribute values such as "keywds" really needed to be in the specified character set and some needed to stay in UTF-8 all the time. Whether the charset for an atribute value changes when an alternative character set is specified must be defined when the attribute is defined. The default is that an attribute value is not dependent on charset. - new (optional) attributes for SDP language and session language have been added so that SDP conforms to the requirements in draft-alvestrand-charset-policy-02.txt Does anyone believe that these changes are sufficient to warrant a new WG last call? Personally I believe they're minor enough we can re-submit the revised draft to Allyn for IETF last call. Cheers, Mark
