Eh?

If a user wants to ‘consume’ (I assume here you mean change the position 
of the document elements), he could write e.g. the following user 
stylesheet for XHTML 2.0 (or let it be generated automatically):

* [role=navigation] {
    position: absolute;
    width: 10em;
}
* [role=main] {
    position: absolute;
    left: 10em;
}

If by ‘consume’ you mean machine processing or user processing of any 
kind, that’s possible given the standardised values on role and has 
nothing to do with CSS.

I literally quote from your guideline no. 2: ‘change the meaning’. And I 
have no clue what you mean with ‘consuming’ (again that word - what does 
it mean in this context?) nor which elements you are referring to as 
‘link link’.

That’s nonsense. CSS is a styling language. XFrames positioning may be 
implemented by means of CSS. Just like in many implementations, <img 
src="" width="50" height="100"/> has its attributes mapped directly to 
the CSS width and height properties, even though those sizes itself are 
meta-information and part of the document.

CSS does not. The positioning part of XFrames may be implemented by 
means of CSS, just like the default rendering of <em> in italics is 
implemented with CSS. The emphasis itself however is marked up 
semantically in the HTML.

Similarly the role of a section containing the navigation of a page is 
marked up semantically with role="navigation", and the actual 
positioning of it is done with CSS.

I see you have significant trouble distinguishing semantics from 
presentation. You want to create a language that does both.
