<?xml version='1.0' encoding='UTF-8'?>
<elementClass name='MyClass' class='GenericBehaviorElement'>
  <behavior type='ECBHelpTopic'>
    <!-- set element properties. omit property prefix if used inside behavior tag -->
    <string name='.topic'>ocls_actormarker</string>
  </behavior>
</elementClass>
</code>
