 * Interface for a DOM serializer implementation.
 * <p>
 * The DOMSerializer is a facet of a serializer and is obtained from the
 * asDOMSerializer() method of the Serializer interface. 
 * A serializer may or may not support a DOM serializer, if it does not then the 
 * return value from asDOMSerializer() is null.
 * <p>
 * Example:
 * <pre>
 * Document     doc;
 * Serializer   ser;
 * OutputStream os;
 * 
 * ser = ...;
 * os = ...;
 *
 * ser.setOutputStream( os );
 * DOMSerialzier dser = ser.asDOMSerializer();
 * dser.serialize(doc);
 * </pre>
