 * 1. disabled (global, value = 0) - all events are registered;
 * 2. absolute (global, value = 1) - alert isn't registered which means that event won't appear in timelines at all;
 * 3. absolute (for Timeline only, value = 21) - the same as global absolute.
 * 4. partial registration might be added in the future versions.
