 /**
  * JAXP {@link javax.xml.transform.Source} implementation
  * that marshals a JAXB-generated object.
  *
  * <p>
  * This utility class is useful to combine JAXB with
  * other Java/XML technologies.
  *
  * <p>
  * The following example shows how to use JAXB to marshal a document
  * for transformation by XSLT.
  *
  * <blockquote>
  *    <pre>
  *       MyObject o = // get JAXB content tree
  *
  *       // jaxbContext is a JAXBContext object from which 'o' is created.
  *       JAXBSource source = new JAXBSource( jaxbContext, o );
  *
  *       // set up XSLT transformation
  *       TransformerFactory tf = TransformerFactory.newInstance();
  *       Transformer t = tf.newTransformer(new StreamSource("test.xsl"));
  *
  *       // run transformation
  *       t.transform(source,new StreamResult(System.out));
  *    </pre>
  * </blockquote>
  *
  * <p>
  * The fact that JAXBSource derives from SAXSource is an implementation
  * detail. Thus in general applications are strongly discouraged from
  * accessing methods defined on SAXSource. In particular,
  * the setXMLReader and setInputSource methods shall never be called.
  * The XMLReader object obtained by the getXMLReader method shall
  * be used only for parsing the InputSource object returned by
  * the getInputSource method.
  *
  * <p>
  * Similarly the InputSource object obtained by the getInputSource
  * method shall be used only for being parsed by the XMLReader object
  * returned by the getXMLReader.
