 * A notification log holds a list of {@link Notification Notifications}, i.e., information about domain events that have occurred and have
12 
 * been stored in an {@link com.reallifedeveloper.common.application.eventstore.EventStore}.
13 
 * <p>
14 
 * A notification log may be <i>archived</i>, which means that it will never change. If a log is archived, it means that the ID of the log
15 
 * will always refer to the current list of {@link Notification Notifications}. If it is not archived, the only change that may occur is
16 
 * that more notifications are added to it; the notifications themselves represent historical events that have already occurred, so they are
17 
 * immutable.
