 * Implements XmlToolsFactory

 * Now this class tries to clean up the mess OSGi and JAXP produce in
 * combination. For XPathFactory and TransformerFactory the implementation
 * directly uses Xalan, since it can be added and already is added.
 * </p>
 * <p>
 * For DocumentBuilderFactory and SAXParserFactory is uses the direct JAXP
 * approach, since there should be no other implementations active at the
 * moment.
