Feedback on ARIA Spec and Best Practices Guide

All-

Attached is my feedback on both the WAI-ARIA Specification, Last Call  
Working Draft and the WAI-ARIA Best Practices Guide.
I hope that it is not too late to submit my feedback.  Let me know if  
you have any questions.  I'd be happy to help out further in any way  
that I can.

Thanks,
Todd
