Well, I would handle it the tedious but efficient way, i.e. listing
all possible cases.

An english book (double sided printing):

:lang(en) {

::vref-current-page { content: "on this page" }
::vref-previous-and-odd-page { content: "on the preceding page" }
::vref-previous-and-even-page { content: "on the facing page" }
::vref-next-and-odd-page { content: "on the facing page" }
::vref-next-and-even-page { content: "on the following page" }
::vref-range-onepage { content: "on page " target-counter(firstref,
page, decimal) }
::vref-range-multipage { content: "on pages " target-counter(firstref,
page, decimal) "\2013" target-counter(secondref, page, decimal) }

}

See the speech <a href="#begin" style="vref: #begin #end">here</a> and
the figure <a href="#fig" style="vref: #fig">there</a>.

Possible rendering:

See the speech on pages 12–15 and the figure on the facing page.


A french and german paper (single sided printing):

:lang(fr) {

::vref-current-page { content: "sur cette page" }
::vref-previous-and-odd-page { content: "sur la page précédente" }
::vref-previous-and-even-page { content: "sur la page précédente" }
::vref-next-and-odd-page { content: "sur la page suivante" }
::vref-next-and-even-page { content: "sur la page suivante" }
::vref-range-onepage { content: "p.\00A0" target-counter(firstref,
page, decimal) }
::vref-range-multipage { content: "p.\00A0" target-counter(firstref,
page, decimal) "-" target-counter(secondref, page, decimal) }

}

:lang(de) {

::vref-current-page { content: "auf dieser Seite" }
::vref-previous-and-odd-page { content: "auf der vorherigen Seite" }
::vref-previous-and-even-page { content: "auf der vorherigen Seite" }
::vref-next-and-odd-page { content: "auf der nächsten Seite" }
::vref-next-and-even-page { content: "auf der nächsten Seite" }
::vref-range-onepage { content: "S.\00A0" target-counter(firstref,
page, decimal) }
::vref-range-multipage { content: "S.\00A0" target-counter(firstref,
page, decimal) "-" target-counter(secondref, page, decimal) }

}


Note that I couldn't use the syntax "target-counter(attr(href, url),
page, decimal)" since we need two hrefs (one for the beginning of the
target, one for its end).  The syntax
"target-counter([firstref|secondref]...)" is certainly wrong but it's
here for clarity.  I let more skilled people inventing a correct
syntax if they think this feature is worth being included in CSS3.
IMO it's a very nice one for people using HTML/CSS to typeset
documents.
