<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."
