Re: [aapi] ARIAAttrModified?

I guess I really don't understand the use case for this?  When/how would I 
expect an AT or a browser to change an ARIA property?  I suspect this may 
have to do with alternative input, such as voice, which I admittedly know 
little about.   For example, I can't imagine coding the Dojo Grid to 
listen for an aria-sort property change and then take the appropriate 
action to re-render the grid.   Given voice input perhaps this would be:
"focus the Country Column Header"
"sort ascending"

The following would happen in response to the above voice commands:   the 
column header labeled "Country" would be focused; then the sort ascending 
action would be performed and the grid re-rendered;  then focus would be 
put back into the column header.  Is this an expected use case?   Can 
someone provide another?  Right now I'm having a hard time accepting that 
we need separate DOM Mutation events just for ARIA.
