/**
 * Executes the state variable query and retuns the UPNP device response, according to the UPNP specs,

 * @throws IOException if some IOException occurs during message send and reception process
 * @throws UPNPResponseException if an UPNP error message is returned from the server
 *         or if some parsing exception occurs ( detailErrorCode = 899, detailErrorDescription = SAXException message )
