    Technically this can be done by mapping a foreign key column as an
    ObjAttribute. Still it would go against the spirit of Cayenne. I
    suggest to use a real ItemType object. DataObjectUtils.objectForPk
    (..) should be a pretty efficient way to get a hold of ItemType
    instance, as after the object is fetched for the first time, it will
    be served from shared cache on subsequent calls.
