DOCBOOK: Error with DBX XSLT sheets 1.22

["E.L. Willighagen" <egonw@sci.kun.nl>]

I have this error, when parsing DocBook XML 4.1.2 with the XSLT sheets 1.22:

========= Parsing file:/vol/www/woc/archief/documentatie/docbook/xhtml/docbook.xsl ==========
Parse of file:/vol/www/woc/archief/documentatie/docbook/xhtml/docbook.xsl took 50042 milliseconds

XSL Error: pattern = '$toc.list.type = 'dl''
VariableReference given for variable out of context or without definition!  Name = toc.list.type, source tree node: #document
Xalan: was not successful.
XSLProcessor: done

I use this script:

#!/bin/sh
XMLSOURCE=osdg.xml
STYLESHEET=/vol/www/woc/archief/documentatie/docbook/xhtml/docbook.xsl
OUTPUTFILE=osdg.html
CLASSPATH=/vol/www/woc/cgi-bin/jars/xerces.jar:/vol/www/woc/cgi-bin/jars/xalan.jar
/usr/bin/java -classpath ${CLASSPATH} org.apache.xalan.xslt.Process -in ${XMLSOURCE} -xsl ${STYLESHEET} -out ${O
UTPUTFILE}

java version is 1.2...

Version 1.19 of the stylesheets gives no errors...
