why not control Saxon directly from Ant ?
You can use the <xslt/> Ant task or use <java/> to invoke saxon...which
may or may not have the built in up to date checking you desire
the following is a macrodef which you can use to invoke Saxon as a task
using <java/>;
<macrodef name="saxon">
<attribute name="current"/>
<attribute name="src"/>
<attribute name="dest"/>
<sequential>
<mkdir dir="${dir.dist}/@{current}"/>
<java classname="net.sf.saxon.Transform"
fork="true"
failonerror="false"
maxmemory="256m">
<!-- these are just saxon specific switches, change as u see fit -->
<arg value="-w1"/>
<arg value="-o"/>
<arg value="@{dest}/@{current}"/>
<arg value="-a"/>
<arg value="@{src}/@{current}"/>
<!-- examples of passing in parameters -->
<arg value="lang=en"/>
<arg value="usedublincore=yes"/>
<arg value="client=web"/>
<arg value="tstamp=${ts.DSTAMP}:${ts.TSTAMP}"/>
<classpath>
<pathelement location="${jar.saxon}"/>
</classpath>
</java>
</sequential>
</macrodef>
though I would suggest trying out the <xslt/> task first...this is a
good example of wrapping up a <java/> call and effectively making it a
new task to call;
you will need to supply the various properties, but to invoke this in
your Targets just do
<saxon current="" dest="" src=""/>
where;
dest= top level dest dir
src= top level src dir
current= specific dir to process under src
it depends on exactly how you have decided to perform transformation to
use such things as <uptodate/>....need a little more info.
