 * A getter and setter must be declared for each property that is not of a managed type or of {@link ModelSet}.
 * For properties of managed types or of {@link ModelSet} the getter is mandatory and the setter is optional.
 * If no setter is provided the property is considered inherent and defaults to an "empty" instance of the type.
