I'm not sure this is the best solution (any comments?), but I ended up  
adding another pass to the processing, since I couldn't get it work  
just using the call-template:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

        xmlns:db="http://docbook.org/docbook-ng";
        xmlns:mods="http://www.loc.gov/mods/v3";
        xmlns:bib="http://xbiblio.sourceforge.net";
        xmlns="http://docbook.org/docbook-ng";
        exclude-result-prefixes="mods bib db xs">
