* JAXBContext context = JAXBContext.newInstance( "org.acme.foo" );
*
* Unmarshaller unmarshaller = context.createUnmarshaller();
*
* UnmarshallerHandler unmarshallerHandler = unmarshaller.getUnmarshallerHandler();

* xmlReader.parse(new InputSource( new FileInputStream( XML_FILE ) ) );
*
* MyObject myObject= (MyObject)unmarshallerHandler.getResult();
*
*
*
* This interface is reusable: even if the user fails to unmarshal
* an object, s/he can still start a new round of unmarshalling.
