/**
* Ant task for batch-compiling XML report design files.
* Works like the built-in <code>javac</code> Ant task.
* <p>
* This task can take the following arguments:
* <ul>
* <li>src
* <li>destdir
* <li>compiler
* <li>classpath
* <li>tempdir
* <li>keepjava
* <li>xmlvalidation
* </ul>
* Of these arguments, the <code>src</code> and <code>destdir</code> are required.
* When this task executes, it will recursively scan the <code>src</code> and
* <code>destdir</code> looking for XML report design files to compile.
* This task makes its compile decision based on timestamp and only XML files
* that have no corresponding .jasper file or where the compiled report design file
* is older than the XML file will be compiled.
