Let me try to be clearer:

You say:

>"The Media Fragment WG has no authority to update registries of all
> targeted media types.

but I do think you have the authority to initiate such a change
by proposing an update to the BCP for registering media types,
and also proposing updates to the target media type registrations.

In order to make this change effective, of course, it will likely
require IETF consensus, but the proposed changes make sense and
improve the use of media types on the web.

I can offer to do an update of the Ogg RFC
http://www.ietf.org/rfc/rfc5334.txt with these fragment

Though, to be honest, it will be easier to just get implementations
and then, if they catch on, update the RFC.

The reason that we can do implementations without much issues is that
virtually no other implementations of fragment schemes on media
resources exist. Even where schemes were developed such as at YouTube,
these schemes were not done on the media resource, but on the Web page
URLs. Also see http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/#ExistingSchemes
for a more indepth analysis of the state of affairs. The exisiting
MPEG scheme has not been implemented anywhere FAIK and would not clash
since it always starts with mp().
