i think using isTextControl() may cast a wider net then we want. won't it include native text controls tools? we should probably limit this to aria text controls, because the native controls are already handled

Ah yes, you're right: I was confused because it checks for textbox AX roles, but they are set for native text boxes as well.

i would move isARIATextControl to AXObject.h so that you don't have to do toAccessibilityRenderObject
That's the direction the code has been moving so that we can abstract away more from AXRenderObject and only have to worry about AXObject
otherwise looks ok to me

Actually, I ended up changing this a bit more significantly: removed the else, and the break above. My reasoning: 
- The method below doesn't break out of the loop when it posts the AXLiveRegionChanged notification, and it seems like the logic should be similar across the two methods (in fact, possibly the loop needs to be refactored out into a common method)
- If there is both aria-live=true and role=textbox, both notifications are relevant

Please note, I also modified the selection-value-changes-for-aria-textbox LayoutTest as part of this update; it was broken by this change before.

thanks. a few thoughts inline

it seems like we should not be sending out two AXValueChange notifications for the same object (For the same value change). 
i suspect we might want to check that an object is only an aria text control and not a standard text control...

it looks like there's already a local instance of axObjectCache() (cache) that can be used here (and also in the live region block)

That makes sense. This is what happens when I try to code the same day as getting off a transcontinental flight.
