Re: Proper use of labelledby vs describedby and definitions

Shane,

I agree with James.

I'll go a bit further and say that I don't think any ARIA is required 
inside the main content of a static document formatted using HTML. The 
HTML has everything needed.

Unless I am forgetting something, The only value-add use of 
aria-labelledby I can think of in the respec formatting that has been 
discussed thus far is to label each of the complementary appendix regions. 
I can not think of any circumstances in the specification document where I 
believe aria-describedby should be used.

I don't see why you would do this. Why would you introduce a description 
of a term which is available only to AT users? If this is useful then it 
should be available to everybody. If you decide that this is useful then a 
link to the term would probably be the best way to accomplish it.
