Michael: see http://www.w3.org/2008/WebVideo/Fragments/wiki/Semantics

<raphael> TBL Quotes: "I think that it would be good to have a general rule for video/* that there is a common fragment identifier syntax and semantics. I think that the specification should claim all video/*. The W3C specification itself can be a media type specification... I think it can be registered in the registry as the spec for a MIME type."

raphael: will approach TAG officially

jackjansen: thought MPEG has its own hands on it?
