Re: ARIA: math role is intended for math images not real math, so it should just be role="img"

Again, great explanation. I'll make an editorial note to clear up the  
description of math by adding the info you mentioned below, but we  
should also consider the following changes:

	1. math should inherit from img. It currently inherits from section.
	2. Note the alt string syntax of math in the spec, and provide an  
example in the BPG.
