/**
 * 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>
