Re: embed (was NEW: Issue #1783)

I agree that we need to do some additional testing on this. I know that 
Lynx displays the value of alt on <embed> and have some old notes that 
indicate that JAWS at one time supported this technique as well.

This is an area of particular importance when it comes to sufficient 
techniques since there are some fairly large gaps between the 
recommendations in the relevant specifications, or current crop of 
techniques and today's realities of browser and AT support.
