Well sure, but that's XML/SXML---it's a specific embedded language.
But what about other languages with different kind of identifier
syntaxes? Say, ML or Haskell. XML may go away again at some point in
the future, and get replaced by a case-insensitive language. I just
don't think this one example is sufficient justification to do
make that kind of sweeping change.

I think that's dodging the issue. Maybe this is what we want to do
(seems to've worked for Matthew), but I'm afraid of the complications
due to it. People are likely to get confused about what mode they're
in (I get confused all the time with PLT Scheme), and get funny
results when they mix case-sensitive and case-insensitive code
inadvertently, especially when using macros. Some module will export
a mixed-case identifier, and somebody in case-insensitive mode is
going to scratch their head. It all smells suspiciously of the worst
aspects of Common Lisp.
Consequently, I'd rather be case-sensitive than case-ambivalent.
