   * Interface for a DOM serializer implementation.
   * <p>
   * The DOMSerializer is a facet of a serializer and is obtained from the
   * asDOMSerializer() method of the ({@link 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>
   * // Create a document to be serialized
   * org.w3c.dom.Document doc = ...;
   * 
   * // Create a Serializer that will be used
   * // to serialize the document  
   * org.apache.xml.serializer.Serializer ser = ...;
   *
   * // Set the Writer to write output to, and 
   * // serialize the DOM using that Serializer
   * java.io.StringWriter sw = new java.io.StringWriter();
   * ser.setWriter(sw);
   * DOMSerialzier dser = ser.asDOMSerializer();
   * dser.serialize(doc);
   * 
   * // Write out the serialized XML in the String.
   * System.out.println(sw.toString());
   * </pre>
