/**
 * This interface is not intended to be used
 * by an end user, but rather by an XML parser that is implementing the DOM 
 * Level 3 Load and Save APIs.
 * 
 * 
 * See the DOM Level 3 Load and Save interface at LSSeializer.
 * 
 * For a list of configuration parameters for DOM Level 3 see DOMConfiguration.
 * For additional configuration parameters available with the DOM Level 3 Load and Save API LSSerializer see
 * LSerializer config.
 * 

 * The following example uses a DOM3Serializer indirectly, through an an XML
 * parser that uses this class as part of its implementation of the DOM Level 3
 * Load and Save APIs, and is the prefered way to serialize with DOM Level 3 APIs.
 * 

 * Example:
 * 
 *    public class TestDOM3 {
 *
 *    public static void main(String args[]) throws Exception {
 *        // Get document to serialize
 *        TestDOM3 test = new TestDOM3();
 *        
 *        // Serialize using standard DOM Level 3 Load/Save APIs        
 *        System.out.println(test.testDOM3LS());
 *    }
 *
 *    public org.w3c.dom.Document getDocument() throws Exception {
 *        // Create a simple DOM Document.
 *        javax.xml.parsers.DocumentBuilderFactory factory = 
 *            javax.xml.parsers.DocumentBuilderFactory.newInstance();
 *        javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();
 *        byte[] bytes = "".getBytes();
 *        java.io.InputStream is = new java.io.ByteArrayInputStream(bytes);
 *        org.w3c.dom.Document doc = builder.parse(is);
 *        return doc;
 *    }
 *    
 *    //
 *    // This method uses standard DOM Level 3 Load Save APIs:
 *    //   org.w3c.dom.bootstrap.DOMImplementationRegistry
 *    //   org.w3c.dom.ls.DOMImplementationLS
 *    //   org.w3c.dom.ls.DOMImplementationLS
 *    //   org.w3c.dom.ls.LSSerializer
 *    //   org.w3c.dom.DOMConfiguration
 *    //   
 *    // The only thing non-standard in this method is the value set for the
 *    // name of the class implementing the DOM Level 3 Load Save APIs,
 *    // which in this case is:
 *    //   org.apache.xerces.dom.DOMImplementationSourceImpl
 *    //
 *
 *    public String testDOM3LS() throws Exception {
 *        
 *        // Get a simple DOM Document that will be serialized.
 *        org.w3c.dom.Document docToSerialize = getDocument();
 *
 *        // Get a factory (DOMImplementationLS) for creating a Load and Save object.
 *        org.w3c.dom.ls.DOMImplementationLS impl = 
 *            (org.w3c.dom.ls.DOMImplementationLS) 
 *            org.w3c.dom.bootstrap.DOMImplementationRegistry.newInstance().getDOMImplementation("LS");
 *
 *        // Use the factory to create an object (LSSerializer) used to 
 *        // write out or save the document.
 *        org.w3c.dom.ls.LSSerializer writer = impl.createLSSerializer();
 *        org.w3c.dom.DOMConfiguration config = writer.getDomConfig();
 *        config.setParameter("format-pretty-print", Boolean.TRUE);
 *        
 *        // Use the LSSerializer to write out or serialize the document to a String.
 *        String serializedXML = writer.writeToString(docToSerialize);
 *        return serializedXML;
 *    }
 *    
 *    }  // end of class TestDOM3
