I see. I was not aware of W3C's discussion about new top-
level media type, but I think the concern was exactly same
with what Murata-san (SC34/WG4 convenor) told us. After
the initial decision (to propose the top-level media type),
SC29/WG11 had found any urgent request to stabilize the
media type for 14496-22?

Excuse me, "application/font-sfnt" is already registered,
and will be mentioned in forthcoming amendment to 14496-22?
Or, the registration of the media type and the publication 
of the amendment is being processed in parallel?

When new top-level media type "font" is approved, SC29/WG11 will
regist yet another media type for 14496-22?
