What kind of use is this about? Is this about XHTML-Print-type stuff  
or about Prince-type high-end formatting? CSS already allows page  
number references, which means that the formatter has to paginate the  
whole document in order to make forward reference by page number.

I have never seen the source of a print-only CSS formatter, but I  
imagine an optimized implementation could optimize away the DOM but  
would still have to keep the entire CSS frame tree in memory (at  
least when there's generated content that depends on later page
