Looking, however, at the definition of wasInvalidatedBy, it seems that 
the activity that invalidated the entity in question is optional. This 
suggests to rename wasInvalidatedBy to wasInvalidated. This observation 
also applies to wasGeneratedBy.

In the definition of wasStartedBy, the trigger is the existence of an 
entity. I think this makes the definition a bit hard to grasp. A natural 
way of defining the start and end of an activity would be with respect 
to an event, which can be, e.g., the generation or the use of an entity, 
etc. Is there a reason why we are trying to avoid the use of notion of 
"event" here?
