/**
 * Interface for a DOM serializer capable of serializing DOMs as specified in
 * the DOM Level 3 Save Recommendation.
 * <p>
 * The DOM3Serializer is a facet of a serializer and is obtained from the
 * asDOM3Serializer() method of the org.apache.xml.serializer.Serializer interface.
 * A serializer may or may not support a level 3 DOM serializer, if it does not then the
 * return value from asDOM3Serializer() is null.
 * <p>
 * Example:
 * <pre>
 * Document     doc;
 * Serializer   ser;
 * OutputStream os;
 * DOMErrorHandler handler;
 *
 * ser = ...;
 * os = ...;
 * handler = ...;
 *
 * ser.setOutputStream( os );
 * DOM3Serialzier dser = (DOM3Serialzier)ser.asDOM3Serializer();
 * dser.setErrorHandler(handler);
 * dser.serialize(doc);
 * </pre>
