Without some mechanism for identifying one of the fonts in a given
TTC, how can we use TTC from CSS fonts?  I am just saying that
the lack of such a mechanism should be clearly described in the
CSS3 Font specification.  If somebody creates a media type for
OT and establishes fragment identifiers for TTC OT, I am happy to
change my mind.

Makoto

In fact, there is nothing in the current spec that would prohibit it, it's just the name itself ("TrueType Collection") implies that its use may be limited to TrueType-flavored fonts only. So, in light of these discussions taking place, it seems much more reasonable to extend the CSS to support TTC rather than restricting its use.
