I have had this clarified in the latest -core IETF draft, section 7.5.3 [1].
You can't have multiple childs of IQ because it opens a whole can of worms:

 - if one of the request inside an iq fails, should actions performed because
   of the other requests be rolled back?
 - which request did actually fail and how do I know?

There are probably a lot more, and I'd rather not go there.
