 /**
  * Enable synchronization between XML infoset nodes and JAXB objects
  * representing same XML document.
  *
  * <p>
  * An instance of this class maintains the association between XML nodes of
  * an infoset preserving view and a JAXB representation of an XML document.
  * Navigation between the two views is provided by the methods
  * {@link #getXMLNode(Object)} and {@link #getJAXBNode(Object)}.
  *
  * <p>
  * Modifications can be made to either the infoset preserving view or the
  * JAXB representation of the document while the other view remains
  * unmodified. The binder is able to synchronize the changes made in the
  * modified view back into the other view using the appropriate
  * Binder update methods, {@link #updateXML(Object, Object)} or
  * {@link #updateJAXB(Object)}.
  *
  * <p>
  * A typical usage scenario is the following:
  * <ul>
  *   <li>load XML document into an XML infoset representation</li>
  *   <li>{@link #unmarshal(Object)} XML infoset view to JAXB view.
  *       (Note to conserve resources, it is possible to only unmarshal a
  *       subtree of the XML infoset view to the JAXB view.)</li>
  *   <li>application access/updates JAXB view of XML document.</li>
  *   <li>{@link #updateXML(Object)} synchronizes modifications to JAXB view
  *       back into the XML infoset view. Update operation preserves as
  *       much of original XML infoset as possible (i.e. comments, PI, ...)</li>
  * </ul>
  *
  * <p>
  * A Binder instance is created using the factory method
  * {@link JAXBContext#createBinder()} or {@link JAXBContext#createBinder(Class)}.
  *
  * <p>
  * The template parameter, <code>XmlNode</code>, is the
  * root interface/class for the XML infoset preserving representation.
  * A Binder implementation is required to minimally support
  * an <code>XmlNode</code> value of <code>org.w3c.dom.Node.class</code>.
  * A Binder implementation can support alternative XML infoset
  * preserving representations.
