* Unmarshaller implemented as SAX ContentHandler.

* in an XML pipeline. For example:
*
* {@snippet :
* JAXBContext context = JAXBContext.newInstance( "org.acme.foo" );
*
* Unmarshaller unmarshaller = context.createUnmarshaller();
*
* UnmarshallerHandler unmarshallerHandler = unmarshaller.getUnmarshallerHandler();
*
* SAXParserFactory spf = SAXParserFactory.newInstance();
* spf.setNamespaceAware( true );
*
* XMLReader xmlReader = spf.newSAXParser().getXMLReader();
* xmlReader.setContentHandler( unmarshallerHandler );
* xmlReader.parse(new InputSource( new FileInputStream( XML_FILE ) ) );
*
* MyObject myObject= (MyObject)unmarshallerHandler.getResult();
* }
*
* <p>
* This interface is reusable: even if the user fails to unmarshal
* an object, s/he can still start a new round of unmarshalling.
