I think the one I created serves that request, doesn't it? If it's  
missing something, please advise.

That's a good recommendation to make, but I don't think it's necessary  
to do that amount of browser checking and rewriting for the example  
code, do you? One caveat though. Instead of maintaining a list of user  
agents that support ARIA, maintain a list of old user agents that are  
known to not support ARIA. Assume the best of unknown user agent  
strings, and serve up the full ARIA support.
