title: Is it possible to use specific ICU library (.jar) in ant xslt task in DITA-OT?
body: <p>I am developing <code>DITA-OT plugin</code> that offers several <em>.jars</em> to be used from other <code>DITA-OT plug-in</code>. </p>
  
  <p>This plugin uses <code>ICU library (http://site.icu-project.org/）icu4j-4_8.jar</code> and must support from <em>DITA-OT 1.7.5</em> to the newest <em>DITA-OT 2.2.1</em>.<br>
  However, I know that <em>DITA-OT</em> bundles <strong>ICU library in DITA-OT/lib</strong> directory. The newest version seems to be <code>icu4j-54.1.jar</code>.</p>
  
  <p>My problem is this <strong>ICU library</strong>. When my plugin is used by xslt task in other plugin, I explicitly specified <code>icu4j-4_8.jar</code> as <strong>xslt/@classpathref</strong>. But, the output result seems that <em>xslt task</em> uses <em>ICU library from DITA-OT/lib</em> directory because of pre-process or other previous steps has already used it.</p>
  
  <p>Are there any ways to <strong>force ant xslt task to use specific ICU .jar</strong> file specified by <em>xslt/@classpathref</em>?</p>
