Hi Jesse,

I tested your code with Firefox 9.01 and JAWS 13, worked fine.

Chrome has a known bug with describedby.(
http://code.google.com/p/chromium/issues/detail?id=89195)

Also note that descibedby ONLY works with IE9+ and mulitple values for
aria-labelledby only works with IE9+

Furthermore IE requires that the referenced elements are either 'accessible
elements' (
http://msdn.microsoft.com/en-us/library/gg701963%28v=vs.85%29.aspx#Accessible_HTML_Elements
) or have tabdindex"-1" added.

so for your example you could do:

<label for="dname">Domain name</label>
<input id="dname" type="text" aria-describedby="helptext win">
<span id="helptext" tabindex="-1">use format: something.com</span>
<div id="win" tabindex="-1">Success! Domain name available</div>


or

<label for="dname">Domain name</label>
<input id="dname" type="text" aria-describedby="helptext win">
<label id="helptext">use format: something.com</label>
<label id="win">Success! Domain name available</label>
