DOM implementation extensions

The DOMImplementation interface continues to hold the original method for checking for the presence of features supported by the parser:

					boolean hasFeature( String feature, String version);
				

But the createDocumentType and createDocument methods have been added, allowing new document types and individual documents to be created from scratch within the DOM:

Document     createDocument(String namespaceURI,
                            String qualifiedName,
                            DocumentType doctype);
DocumentType createDocumentType(String qualifiedName,
                                String publicId,
                                String systemId);

For example, the Xerces parser implements this interface in a class called DOMImplementationImpl:

 import org.apache.xerces.dom.DOMImplementationImpl; ... DOMImplementationImpl myDOMImpl ...
