I think this was due to a late (and inadvisable) change of 'Unicode"
to 'ISO 10646' throughout the CSS2 document in response to some
comment or other.

Which makes no particular sense for the places where they are
equivalent (character repertoire) and is completely wrong for areas
where Unicode provides per-character data beyond 10646.

Like Michel, I would support changing 10646 to Unicode throughout,
with an explanatory not in the refs section briefly describing that
10646 and Unicode are aligned.

The get-out clause for that funky non-Basic-Latin wierdo international
text ;0) while perhaps understandable in 1997-1998 also looks quaint
and antiquated in 2003 and should be removed in CSS2.1; its just
another undesirable difference between "HTML" and "XHTML or generic
XML" CSS renderers.

Instead, just say that the text-transform does what the Unicode case
conversion tasbles say and thats it. Simple, reliable, interoperable.
