It might just be a semantic issue. Other locational nouns seem to either imply a direction or are used with an implied {naDev}, so something like {DungDaq} on its own could perhaps be used for "upwards, towards a general above-area" or "above here". But the notion of "beyond" doesn't really imply a direction, and it's defined relative to "here" so you'd need to reference a second point. With the right context you could probably get away with a lone {Hay}. {HayDaq ngem wIchIq} makes sense to me, for instance.
