RE: Proper use of labelledby vs describedby and definitions

>Just for my edification, can someone explain how an AT would know and convey where the definition of a term was in the following scenarios?

 

This is what I was referring to earlier, isn’t the below valid based on

http://www.w3.org/TR/wai-aria/states_and_properties#aria-flowto

?

 

<dl>

   <dt id='def-my-term'>My Term</dt>

   <dt id='def-my-other-term'>My Other Term</dt>

   <dd>A definition of both My Term and My Other Term, which are roughly synonyms.</dd>

</dl>

 

<p>Some prose in which I reference the formal term <a href='#def-my-term' title='My Term' aria-flowto=”def-my-term def-my-other-term” >My Term</a> in the course of discussing whatever.</p>

Huh.  Okay.  

 

Just for my edification, can someone explain how an AT would know and convey where the definition of a term was in the following scenarios?

 

<dl>

   <dt id='def-my-term'>My Term</dt>

   <dt id='def-my-other-term'>My Other Term</dt>

   <dd>A definition of both My Term and My Other Term, which are roughly synonyms.</dd>

</dl>

 

<p>Some prose in which I reference the formal term <a href='#def-my-term' title='My Term'>My Term</a> in the course of discussing whatever.</p>

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.

Also, when referencing a defined term elsewhere, should we also use describedby and point back to the terms description?  E.g., <p>I have some content where I am talking about <span class="internalDFN" aria-describedby="someID">theterm</span> and relating it to other things.</p> 
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.
