Of course, but it's not all in the standard.  There's also at least
one technical report, but it's a long time since I read the stuff.

That's infeasible and it's a waste of time to try.  For instance, in
British English there aren't mechanical rules about title case --
Hart's Rules just says `important words' -- and it doesn't make sense
for Emacs to try to DTRT.

It isn't worthwhile trying to do special casing in Emacs 21, and there
are more important things to sort out in Emacs 22 in case it's ever
released.  Normalization and proper locale handling are a couple, and
case folding depends on them anyway.
