Something similar also already worked for me (with Daniel Veillard's
patch, mentioned in this thread). The "problem": This is not, how
docbook-xsl inbounds parameters (they are in a separate XSL file
param.xsl, the is included by docbook.xsl using xsl:include). I attached
sample files to test the issue (arcticle.001.xml was just taken from the
testdocs SVN directory of docbook-xsl). With these files you should be
able to reproduce the problem. The results are:

$ xsltproc --xinclude xinclude.xsl article.001.xml
=> Read content of xinclude-inc.txt: "failure"

$ java -cp "/usr/share/java/saxon.jar:/usr/share/java/xercesImpl.jar" \
    -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl \
    -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl \
    -Dorg.apache.xerces.xni.parser.XMLParserConfiguration=org.apache.xerces.parsers.XIncludeParserConfiguration \
    com.icl.saxon.StyleSheet article.001.xml xinclude.xsl
=> Read content of xinclude-inc.txt: "success"

$ java -cp "/usr/share/java/xalan2.jar:/usr/share/java/xercesImpl.jar" \
    -Dorg.apache.xerces.xni.parser.XMLParserConfiguration=org.apache.xerces.parsers.XIncludeParserConfiguration \
    org.apache.xalan.xslt.Process -in article.001.xml -xsl xinclude.xsl
=> Read content of xinclude-inc.txt: "success"

It exists.

Yes, it does :)
