[xquery-talk] Order of results

Good question.
To me this looks like a bug.  While many things in xquery dont return 
the order one may 'naturally suspect' I belive this case is well 
defined.  Since your using the sequence expression operator (',") then I 
belive this applies to 3.3 of the xquery spec



[Definition: One way to construct a sequence is by using the*comma 
operator*, which evaluates each of its operands and concatenates the 
resulting sequences,*in order,* into a single result sequence.]

But since you didn't provide the full input and code I cant tell for 
sure if maybe there is something fishy elsewhere.
