> Cayenne uses expression like {{src.id = dst.fk}} as a join clause and this is hardcoded for now.
> We can extend this to accept any {{Expression}}.
> This will require redesign in Modeler DbJoin creation dialog and some changes in SelectTranslator. Also this may touch some logic that depends on {{DbRelationship.isSourceIndependentFromTargetChange()}} method.
