Dear colleagues,

I think that we can agree on the following things:

- It would be nice if TTC can be supported by CSS Fonts.

- On top of a reference to a TTC, we have to specify a font name for
    locating a specific font in the given TTC.

- Fragment identifiers look promising as a means for specifying
  font names.

- Font names as fragment identifiers should be documented
  as part of the registration of the media type for OpenType.  (See RFC 4288)

The registration of a media type for OpenType has been discussed for
years and nothing has been registered.  Several private media types have been
widely used.  I do not know if there is a plan (rather than a hope) for

I don't know when CSS Font Level 3 will become a CR, but I think
it should should explain the current status and stop there.
