ID case sensitivity still not explained

The validator gave me an "already defined" error when
I used IDs that differ 
by case only, but
http://www.w3.org/TR/html401/struct/global.html#h-7.5.2

says "id = name [CS]," which means id is case
sensitive and IDs that differ by case should be
considered unique and not produce "already defined"
errors. A similar case was 
discussed in the thread beginning at 
http://lists.w3.org/Archives/Public/www-validator/2001Jul/0016
and 
continuing at
http://lists.w3.org/Archives/Public/www-validator/2001Jul/0046

..

At
http://lists.w3.org/Archives/Public/www-validator/2001Jul/0075
it says 
the wording will be changed, but the wording at 
http://www.w3.org/TR/html401/struct/global.html#h-7.5.2
still doesn't tell 
me that can't use IDs that differ only by case. Am I
looking at the wrong 
specification? I felt proud of myself for being able
to find what seems to 
be the relevant part of the latest HTML specification
by navigating the not 
so user friendly information starting at w3.org, but
now I'm not so sure.

P.S. Why haven't I been able to subscribe
mail@polisource.com or barry@polisource.com to this or
www-html@w3.org for the last few years?
