He creado un documento XML utilizando DOM en java. No puedo agregar doctype. Quiero el doctype así.

<!DOCTYPE IndInfo PUBLIC "EDAFileSomething" "EDAFileSomething_2_0.dtd">

Aquí está el código de creación del documento.

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();

Aquí está el código del objeto del transformador.

TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = null;
            try {
                transformer = transformerFactory.newTransformer();
            } catch (TransformerConfigurationException ex) {
                Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex);
            }
            DOMSource source = new DOMSource(doc);
            try {

                StreamResult result = new StreamResult(System.out);
                transformer.transform(source, result);
            } catch (TransformerException ex) {
                Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex);
            }

            System.out.println("File saved!");
