Activities, entities and involvements like Usage and Association have
in a broad sense all durations. However DM only talks about activity
durations, and the others have/are 'events', so we should keep the
focus there for now, and rather raise it as a requirement to DM if we
can think of a good use case.

I would assume they are non-empty durations in almost every use case.
