[xsl] FO: Cross references in books

[Gustaf Liljegren <gustaf.liljegren@xxxxxxxxxxxx>]

I made an <xref> element with an "idref" attribute in my DTD. Then some
block elements have "id" attributes. I thought this would be handy when I
do cross-references, like in:

<p>Read more about Iraq on page <xref idref="iraq"/>.</p>

I'm trying to implement an <xref> template in XSL-FO now, but with no luck
so far. I don't know how to extract the page number on the other page.
Maybe it's not possible?

Gustaf
