I don't think anything in this spec is format-specific and as such can be applied to Ogg and others, too. The discussion was certainly meant to come up with an open spec usable for any format. The description mentions WebM at times but I have regarded that as a placeholder. If you spot anything that's not generally applicable, please do raise it!

Cheers,
Silvia.
