An example is better than trying to explain and failing. Still, please
note that keeping counters won't help you since the formatting is done
after the XSLT stage. You can simply forget about trying to keep track
of page numbers in XSLT.

With XSL-FO 1.0 you can use an empty fo:block at the end of the fo:flow
and reference that in a fo:page-number-citation.
-->invoice2fo10.xsl

With XSL-FO 1.1 you can set an "id" on the page-sequence and reference
that using fo:page-number-citation-last.
-->invoice2fo11.xsl

Both example use IDs. Since you have multiple invoices (i.e. multiple
page-sequences), you have to generate unique IDs. If you have a unique
number for each invoice you can use that. Otherwise, you can simply use
the index of the invoice in the XML file as I have done in the example.

invoices.xml is just some data to make the transformation go.
