Re: [xsl] XSL + Java extensions + Xalan

Thanks Jean!

Actually, our Sr. Project Manager/über-developer was able to get it to work.

Relevant XSLT tagging:

<xsl:stylesheet
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
	xmlns:lxslt="http://xml.apache.org/xslt";
	xmlns:testIndent="testExtensions"
	extension-element-prefixes="testIndent"
	version="1.0">

<lxslt:component prefix="testIndent" elements="init" functions="setIndent">
	 <lxslt:script lang="javaclass" src="testExtensions"/>
</lxslt:component>

<xsl:template match="myTag">
<xsl:value-of disable-output-escaping="yes" 
select="testIndent:setIndent(string(@indent))" />
</xsl:template>

There was also a necessary change to either the .java file or the location 
of the .java file that she mentioned, but I can't remember those details off 
the top of my head...
