Hi,
I tried converting this appendix to an RFC. Also a plan is to make it more commonly appendable to all the Ogg codecs, thus it should be extended with FLAC, Theora and Speex descriptions.
Both the XML source (I have used xml2rfc - xml.resource.org) and the converted txt is attached. I am curious about your comments. The rfc could have some rewording, style changes and bla bla. Also other reference bibliographic entries to the formats are needed.
i like the idea, i also agree that theora, flac, ... should be added [...]

we should clarify the big/little endianness (IIRC it was little) for a little appendix in the messy vorbis spec it wouldnt have mattered but for a RFC IMHO it does ...

8.7. Quicktime / MPEG4
Quicktime lacks an unambigous place for a global header so its outside the scope of this document.
we could add mov to the list of supported containers if we define a chunk for the global header, other codecs have their own codec specific global header chunks too, maybe "glbl" could be used if its not taken yet, but i need to look more carefully at the mov/qt spec so we unambiguosly define and place it about .mp4, that wasnt covered by the quicktime/mov point, it has a ESDS atom into which a global header can be put, but iam not very familiar with the mpeg4-systems / iso-mp4 container specs so i didnt mention it PS: please svn commit it so we can work on it easier ...
