I always figured it was a defect in EOF in that it did not enforce relation().count() > 0. IIRC, we added that in our validation framework. It is perfectly valid in ER modelling to have a 1..N relationship, so I would not consider this to be a model error.

If a relationship is marked to-many, should entity modeler disallow marking that mandatory? Should it error? Should it warn? I think at the very least it's a warning, and quite possibly should be not allowed.
