//     these notification. Each notification has unique number
//     (or EventCode or NotificationCode) for a given connection
//     object or for the whole system. This depends on implementation.
//     Using system unique NotificationCodes is a preferred way to avoid
//     potential errors with intersected NotificationCodes.
