No the result is not undefined, because a model always takes care of its
content. In particular the standard item model assumes it has ownership of
all its items, thats (IMHO) quite a natural thing to expect from a model
and hence doesn't need explicit documentation.

And in any case, if you're unsure, use the source ;)
