We already have such a mechanism in CSS, in gcpm:
  content: target-counter(attr(href, url), page)

I omitted that since I don't need to propose it. A full solution would
be using something like

a::::before  {
  content: target-counter(attr(href, url), page)
}

There's a minor detail to resolve here relating to pages whose
formatted numbers are not arabic numerals (e.g. prelims with i, ii, iii
etc, or an apendix B-1, B-2) and the formatter needs to work with the
value of the global page counter rather than the formatted string.
