Enforcing XLTC to recompile a Translet

[Postmaster Wolterink Webdesign <po...@wolterinkwebdesign.com>]

I have an webapplication that
uses xsl transformations heavily,
therefore i use xsltc to improve speed,

My xsl files refer to a couple of other xsl and xml files,
like this:

<xsl:variable name="structure" select="document('../../structure.xml')"/>
<xsl:include href="./standard.xsl"/>
<xsl:include href="../../../style/layout.xsl"/>

What i want:
If i change any of the xml/xsl documents then the
Translet should be recompiled. (I dont know if this is
neccesary for the $structure variable)

What i have now:

    private void setupTransformerFactory(TransformerFactory factory) {
        if(this.useXslCompiler) {
            factory.setAttribute("translet-name", "Xcm");
            factory.setAttribute("destination-directory",
                
filterConfig.getServletContext().getRealPath("/WEB-INF/classes/")
            );
            factory.setAttribute("package-name", "translets");
            factory.setAttribute("generate-translet", Boolean.TRUE);
            factory.setAttribute("auto-translet", Boolean.TRUE);
        }
    }

The auto-translet param is set to true, so it should recompile if the 
main xsl file
is edited (am i right?).
But it does not work, the Translet is not recompiled!
How can this be?

On the xalan site i read:
--
auto-translet:
Specifies that time-stamp of translet file, if any, should be compared 
with that of stylesheet to decide whether to recompile the stylesheet
--


But this does not work..
How can i get what i want ( recompilation if any of the xsl files change)?


Some system info:
Webapps runs on Tomcat 5.5.9
JVM 1.5.0_03
Xalan-j: 2.7.0
