xinclude question

[Markus Innerebner <markus@innerebner.net>]

Hello

I am trying to use xinclude in my docbook. But I have following problem.
I am starting the converting via ant with the target xslt as following:

    <target name="dbk2fo" description="Converts docbook xml to fo">
        <xslt in="${properties.docbook.file}" 
out="${properties.docbook.foFile}" 
style="${properties.docbook.foStylesheet}"/>
    </target> 

Than I have a file Introduction.xml that should be include in the main 
document, called Article.xml with following format>

<?xml version="1.0" encoding="UTF-8"?>
<article
  xmlns:xs="http://www.w3.org/2001/XMLSchema";
  xmlns:xi="http://www.w3.org/2001/XInclude";
  xmlns="http://docbook.org/ns/docbook";

    <xi:include href="Introduction.xml"

      <xi:fallback>
        <para><emphasis>File Introduction.xml not found!!! 
</emphasis></para>
      </xi:fallback>
    </xi:include>
  </section>
</article>


The file Introduction.xml has following content:
<?xml version="1.0" encoding="UTF-8"?>
<section xmlns="http://docbook.org/ns/docbook";>
  <title>Introduction</title>
  <para annotations="Motivation">
    Some other text .....
  </para>
</section>

When I am launching the ant I get following error message:
dbk2fo:
     [xslt] Processing 
/data/dev/uni/workspaces/Bz10mServer/docs/systemDescription/Article.xml

     [xslt] xi:include encountered in section, but no template matches.
     [xslt] xi:fallback encountered in xi:include, but no template matches.

Do I need to add something in the parameter of the ant task?
