Hi

I try to include the file intro.xml into the file book.xml but i always
obtain the following error:

C:\Beispiele\Docbook>ant doc2html
Buildfile: build.xml

doc2html:
     [xslt] Processing C:\Beispiele\Docbook\src\docbook.xml to C:
\IBMDiplom\Beis
piele\Docbook\output\docbook.html
     [xslt] Loading stylesheet C:
\DocBook\DocbookDTD\docbook-xsl-1.60.1\html\doc
book.xsl
     [xslt]
C:/DocBook/DocbookDTD/docbook-xsl-1.60.1/html/docbook.xsl:76:16: War
ning! No template matches xi:include in book.

Here both files, first book.xml

<?xml version='1.0'?>
<!DOCTYPE book SYSTEM "file:///C:
\DocBook\DocbookDTD\docbook42\docbookx.dtd">
<book>
      <bookinfo>
            <title>XInclude Test</title>
            <author>
                  <firstname>Klaus</firstname>
                  <surname>Binder</surname>
            </author>
      </bookinfo>
      <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href=
"chap1.xml"/
</book>

Now the file which shall be included: intro.xml

<?xml version='1.0'?>
<!DOCTYPE chapter SYSTEM "file:///C:
\DocBook\DocbookDTD\docbook42\docbookx.dtd">
<chapter id="chap1">
      <title>To be included</title>
      <para>
            Insert this text
      </para>
</chapter>

Has someone an advice for me?

Thank you in advance
