I agree that 18.2.4 is wrong : group-aggregate-having is right. What's 
more it is done in the algorithm box, not in the HAVING section of the doc.

I've rq25 changed put the order right and to put the HAVINg processing 
in an algorithm box in the HAVING section.  (alternative, collapse into 
one section for group-aggregate-having; I mildly prefer keeping it split).
