Hi again Bob

I changed the makefile to:

sax:
                rm -rf site
                mkdir site
                cp css/* site
                cp js/* site
                xmllint --noent --xinclude \
                module.xml > /tmp/docbresolved.xml \
                2>./errloglint
                java com.icl.saxon.StyleSheet \
                -x org.apache.xml.resolver.tools.ResolvingXMLReader \
                -y org.apache.xml.resolver.tools.ResolvingXMLReader \
                -r org.apache.xml.resolver.tools.CatalogResolver \
                -u \
                -o site/index.html \
                /tmp/docbresolved.xml \
                docbook.xsl \
                base.dir="site" \
                use.extensions=1 \
                2>./errlogxslt
                tar czf site.tgz site/*
                echo "site.tgz ready for deployment"

The catalog should then translate 'docbook.xsl' to

    <uri
        name="docbook.xsl"
        uri=".docbook/docbook.custom.xsl" />

The output from verbosity 4 is:

make: *** [Makefile:23: sax] Error 2

which as far as I can see is correct

the error message is now:

Error at xsl:import on line 15 of file:/usr/share/xml/docbook/xsl-stylesheets-1.79.2/xhtml5/chunk.xsl:
  A stylesheet cannot import itself
Transformation failed: Failed to compile stylesheet. 1 error detected.

This puzzles me because I use the same stylesheet when I run with xsltproc without problems.

The installation has:
nmlX240 TheModelChapter  $ ls /usr/share/xml/docbook
docbook-xsl-1.79.2  xml-dtd-4.2  xml-dtd-4.4  xsl-stylesheets-1.79.2
xml-dtd-4.1.2       xml-dtd-4.3  xml-dtd-4.5  xsl-stylesheets-1.79.2-nons


Cheers
/Niels
