The original idea was to use the DDD concept for aggregate, as described
briefly 
http://fornax.itemis.de/confluence/display/fornax/3.+Advanced+Tutorial+(CSC)#3.AdvancedTutorial(CSC)-Aggregate
here .

You can define 'not aggregateRoot' on an Entity to indicate that it belongs
to a parent aggregate.

Maybe that is not enough. Maybe we should make it possible to define
aggregation on reference also.
