HTML is neither a formatting language nor a presentation language.

CSS is more accurately compared to any client-side scripting language than
to HTML.  HTML is a *markup* language.  As with JavaScript, CSS adds
functionality (especially in newer versions) as well as visual, etc.
enhancements.

HTML was not meant to be a programming language, or a language that
provided any sort of functionality, so the need for variables really isn't
that great.  In SGML, the only thing close is the !ENTITY declaration, but
that really doesn't add all that functionality -- only a few abbreviations
here and there.

Really?  That's news to me.  I heard that was a possibility in XSL,
however small, but definitely not XML, which is just an application of
SGML.

What I see is a DTD (possibly something like MML) where some type of
external style sheet (be it written in CSS, XSL, or even some sort of
scripting language (like JavaScript)) processes the markup to give you the
desired calculation.  But, IMHO, markup languages alone aren't really
supposed to do that.
