The source of the document is the following:
<%@page
import="java.io.*,java.net.*,javax.xml.transform.*,javax.xml.transform.s
tream.*"%>
<%@ taglib uri='http://java.sun.com/jstl/core' prefix='c' %>
<%@ taglib uri='http://java.sun.com/jstl/xml' prefix='x' %>
<c:set var="xsl"><c:import
url="style/default/chapter_content.xsl"/></c:set>
<c:set var="xml"><c:import url="source/${param.id}/index.xml"/></c:set>
<x:transform xml="${xml}" xslt="${xsl}"
xsltSystemId="style/default/chapter_content.xsl"/>
And the XSL-stylesheet contains the following beginning:
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:import href="omobj-mathml.xsl"/>
<xsl:output
method="xml"
omit-xml-declaration="yes"
encoding="iso-8859-1"
indent="no"/>
.... Rest of XSL file ....
Any hints greatly appreciated ;)
Manfred.
