Actually, XSLT changes the DOM and therefore the semantics of the  
document... From what I understand of STTS it would not do such a thing.

What CSS namespace, exactly? Or is this just some theoretical concept?  
(CSS declarations can appear inside style="" attribute constructs. Such a  
style="" attribute is available in various markup languages, including

modifications necessary.
