xsl-stylesheets/manpages

Hi,

Because I'm making the french translation of the Openjade and OpenSP man 
pages, I need to customize the docbook.xsl stylesheet provide by xmlto.

Infortunately, more I read about xml and xslt, less I understand. So I hope 
find some help on the list.

I want to add two refsect1 ( TRANSLATION and REVIEWING (of course, in french)) 
after the AUTHORS section, using the <othercontrib> tag.
Here is a piece of the xml source :

<?xml version='1.0' encoding="ISO-8859-15"?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
 "/usr/share/sgml/docbook/xml-dtd-4.1.2-1.0-8/docbookx.dtd">
