Joseph,

I saw the following text in the below referenced section:

> Toggle buttons such as the "Play" button in a media player whose 
> label can switch between Pause" and "Play" depending on its toggle 
state. 

I propose the word toggle should be removed. A toggle button has 
aria-pressed set and this causes screen readers to say pressed or not 
pressed or something along those lines. If the button label changes, 
aria-pressed should not be used. If aria-pressed were used, most screen 
readers would read it as "Play button pressed" and Pause button not 
pressed". That doesn't make sense.

I propose:
"Buttons such as the "Play" button in a media player whose 
label can switch between Pause" and "Play" depending on its state."

It is documented as doing so in the Accessible Name/Description 
Computation and Mappings document:
http://rawgit.com/w3c/aria/master/accname-aam/accname-aam.html#events


I will create a link from the core-aam.html events section to the events 
section of the accname-aam.html.
