RE: XHTML/XML comment

One background reason may be that defining "case insensitive"
for all of Unicode is non-trivial.  How should (German) sharp
s (ß) be handled? It's uppercase is "SS", so is ß equivalent to
"ss"?  What about Turkish dotless i and dotted i? Same or not?
How about Greek iota subscripts? Uppercasing turn them into
ordinary iotas, which remain ordinary iotas when lowercasing
again.  There is some work on this in UTR 21, but I don't think
that is stable yet. 

The easy thing to do, when you can, is to say "case sensitive"
rather that the tricky "case insensitive".
