Hi Jirka,
Thanks for that information. I must be doing something wrong:

I copied the stylesheet from that thread, removed the semicolons from
the header element so it looks like this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                xmlns:saxon="http://icl.com/saxon";
                xmlns:lxslt="http://xml.apache.org/xslt";
                xmlns:redirect="http://xml.apache.org/xalan/redirect";
                xmlns:exsl="http://exslt.org/common";
                xmlns:doc="http://nwalsh.com/xsl/documentation/1.0";
		xmlns:ch="http://docbook.sf.net/xmlns/chunk";
		version="2.0"
                exclude-result-prefixes="doc ch saxon lxslt redirect exsl"
                extension-element-prefixes="saxon redirect lxslt exsl">

the semicolons seemed to be errors when I tried running saxon9.
I then replaced the original 'html/chunker.xsl' with the resulting file.

I ran the following command:

java -jar saxon9he.jar qcug.xml \
/AppDocs/xml/docbook/xsl-1.76.1/html/chunk.xsl \
current.docid=qcug \
target.database.document=olink.xml

and got this result:
