public interface DomHandler<ElementT,ResultT extends javax.xml.transform.Result>
Converts an element (and its descendants) from/to DOM (or similar) representation.
Implementations of this interface will be used in conjunction with
XmlAnyElement annotation to map an element of XML into a representation
of infoset such as W3C DOM.
Implementations hide how a portion of XML is converted into/from such DOM-like representation, allowing JAXB providers to work with arbitrary such library.
This interface is intended to be implemented by library writers and consumed by JAXB providers. None of those methods are intended to be called from applications.
When a JAXB provider needs to unmarshal a part of a document into an infoset representation, it first calls this method to create a

A JAXB provider will then send a portion of the XML into the given result. Such a portion always form a subtree of the whole XML document rooted at an element.
