DOCBOOK-APPS: Need help with xalan 2.1.0

[Eric Richardson <eric@milagrosoft.com>]

Hi,
Trying to get xalan 2.1.0 to work with the 1.41 stylesheets.

Here is the error.
XSLT Error (javax.xml.transform.TransformerConfigurationException):
Namespace not supported by SAXParser


Here is my driver file.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version='1.0'
                xmlns="http://www.w3.org/TR/xhtml1/transitional"
                exclude-result-prefixes="#default">

<xsl:import href="../docbook-xsl/xhtml/docbook.xsl"/>

<!-- override variables defined in param.xsl -->
<xsl:variable name="toc.section.depth">3</xsl:variable>
<!-- Add other variable definitions here -->
<xsl:param name="base.dir" select="'html/'"/>
<xsl:param name="use.id.as.filename" select="1"/>
<xsl:param name="html.encoding" select="'ISO-8859-1'"/>
</xsl:stylesheet>

Any help appreciated.
Eric
