<elementClass name='MyClass' class='GenericBehaviorElement'>
  <behavior type='ECBehaviorComponent'/>
  <behavior type='ECBehaviorCollider'/>
  
  <behavior type='ECBehaviorShowElement'>
    <!-- optional: use BaseGameApp trigger table. game can add more supported values.
                   default is 'default' -->
    <string name='triggerTable'>default</string>
    
    <!-- set element properties. omit property prefix if used inside behavior tag -->
