The current XQuery 3.0 spec does not talk about implicit iteration for dyn func invocation. But I remember Ghislain syaing that he will try to add implicit iteration to the spec. Don't know if he tried and failed, or did not try at all, or whether he actually succeeded and it just has not been made public yet.

But no matter what, this is a case where I wouldn't mind a slight divergence from the official spec as the resulting implementation is much cleaner and actually more general as well. 

Furthermore, I think we should get rid of the ZORBA_WITH_JSONIQ compiler flag and use an option to enable/disable jsoniq. So, we can get back to 100% XQuery conformance by disabling jsoniq.
