It is weird but it's existing behavior. There's already a mish-mash of case-sensitive *and* ASCII case-insensitive rules in use across HTML/CSS and in the Javascript interfaces used to interact with these. Defining CSS identifiers to be case-insensitive using simple case folding may seem locally optimal but I think it's not globally optimal since it effectively introduces a third rule for case sensitivity. I don't think it makes sense to use a different kind of case sensitivity just for identifiers in CSS. Regards, John Daggett
