exactly, and a FO mentioning Heading are required OR you fail, don't fit the possibility of other structural solutions, this is why a must for using heading is also not a A or AA I think. Example: you have a page for a big form with some tables and you use properly Captions for the tables and Legends for the fieldsets, is this a fail because you do not use Headings although they might "look like Headings"?
