You can use macrodefs to make it more readable to others.
First define a macrodef something like as follows
<macrodef name="forked-xslt">
<attribute name="in"/>
<attribute name="out/>
<attribute name="style"/>
<sequential>
<java jar="${saxon}" fork="true" failonerror="true" maxmemory="256m">
<arg value="-s:@{in}"/>
<!-- XSLT stylesheet -->
<arg value="@{style}"/>
</java>
</sequential>
</macrodef>
Now you can invoke the macrodef as follows
<forked-xslt in="command-spreadsheet.xml" out="out.xml" style="intermed.xsl"/>

Subject: Re: Increase Java heap within xslt task?
I assume you mean running the java task with the fork attribute set to
true, not the xslt task. Nothing is wrong with using the java task, but
I thought it might be a little easier for someone else to understand if
I used the xslt task instead. But this seems like more trouble than it
is worth.
Thanks for your help!
