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 numbers).
TeX uses repeated passes over a long document to handle cross-references
properly using limited memory. It would be useful if HTML allowed
something like that.
