CSS and case-sensitivity

One thing that bothered me when I was learning css a few years ago is that
most of the tutorials/guides out there (even the ones from some "experts")
ignore case-sensitivity issues.

They'll usually say something like: for element <p></p>, write a selector P
{}. Usually the reason given is so the capital letters will "stand-out" from
the rest of the text. This was the same reason given for capitalizing html
tags 5 years ago... Now that xhtml is case-sensitive lower-case, shouldn't
css be too?

You can use css on any xml file and since xml is case-sensitive, what's to
differentiate <thisTag /> from <THIStag />... Shouldn't the css selectors be
thisTag and THIStag?

Maybe they are and the browsers just don't care yet. Will someone please
shed light on this for me? Thanks in advance.
