> By viewing an Entity as a composite of an Immutable Identity and a single Value, we end
up with easier transactional semantics, and a generic "Merge" facility could be created.
> For Entities with a lot of properties, where only a small number change each time, we
would recommend that the static part and the dynamic part are implemented as two sub-entities,
or a main entity with all static bits and a sub-entity with the changing data.
