Doesn't this constitute a lost opportunity? So CSS is supposed to
format SMGL style languages that may encode data a certain way and use
attributes and not child elements for storing stylisitic data? Isn't
that just another word for HTML and XHTML?

How about we call CSS for what it is, the styling side of XML/HTML and
be done with it. If we admit that, we at least get to design them in
tandem with each other in mind. Not admitting that doesn't get us
anywhere since CSS can't effectively be used outside SMGL
