Problem with cross references and xincludes

[Bill Lawrence <lawrence@mayaviz.com>]

I'm using xincludes and I'm having a problem with xrefs generating ? for 
page numbers in the PDF output, although it's getting the titles 
properly.  I'm using the 1.68.1 version of the stylesheets, and I've set 
insert.xref.page.number to "maybe".  I'm specifying the page number 
formatting using the xrefstyle attribute on the xrefs.  My xsl processor 
is xsltproc and the FO formatter is XEP.

Thanks in advance,

Bill Lawrence
