EMF itself does not prevent creating invalid states and so doesn't EMF
Forms, which does not add any additional logic here. Validation is
checking a current model instance against those rules. However, for some
model constraints it would be possible to enforce them beforehand.
I assume you talking about multiplicities? They could actually be
enforced by multi-attribute and multi-references controls, but that
would require some customization.
