Was there supposed to be an attachment? I did not received anything.

For the rest, I like the idea (especially point 1) but:

CSS is based on “levels” (some people, no name mentioned, expressed  
how the “level” idea is a posteriori a wrong one, since it  
increasingly limits CSS - still, it is there). Levels mean that older  
parsers will just ignore new rules, but that old rules will still be  
readable. By changing the syntax, your proposal breaks this...

...Except if you can do some content-negociation based on the CSS  
level the UA recognises. I'm know very few of XML, but the way I see  
it, it is impossible to use XSLT to transform CSS “new-syntax” to CSS  
“old-syntax”. Good news is that, *maybe*, this is not necessary and  
another string-replacement language will suffice.

Any input, someone?
