  <p>
  This class enables pre and post processing of an instance of a JAXB mapped class
  as XML data is unmarshalled into it. The event callbacks are called when unmarshalling
  XML content into a JAXBElement instance or a JAXB mapped class that represents a complex type definition.
  The event callbacks are not called when unmarshalling to an instance of a
  Java datatype that represents a simple type definition.
  </p>
  <p>
  External listener is one of two different mechanisms for defining unmarshal event callbacks.
  See <a href="Unmarshaller.html#unmarshalEventCallback">Unmarshal Event Callbacks</a> for an overview.

	Callback method invoked after unmarshalling XML data into <code>target</code>.
	</p>
	<p>
	This method is invoked after all the properties (except IDREF)
	are unmarshalled into <code>target</code>,
	but before <code>target</code> is set into its <code>parent</code> object.
	Note that if the class of <code>target</code> defines its own <code>afterUnmarshal</code> method,
	the class specific callback method is invoked before this method is invoked.</div>
