In bug 533573, Mike added both aria-labelledby and aria-describedby attributes to a group of radio buttons that have no actual label, but are all made up of compound xul:description elements. See http://hg.mozilla.org/labs/weave/rev/90dc7f54c13f for the actual patch. While the aria-labelledby assignment works, in all three instances, the aria-describedby assignment is not picked up even though the IDs match. NVDA doesn't speak the descriptions. This is the case for Firefox 3.5/Gecko 1.9.1 and 3.6/Gecko 1.9.2, haven't checked with mozilla-central yet, but suspect it to be the same. Any ideas?

In contrast, this one from the Advanced/Networking tab of Tools/Options works fine: http://mxr.mozilla.org/mozilla-central/source/browser/components/preferences/advanced.xul#211 But this uses the @control attribute on a description element to point to the button.

Marco, please could you give me steps to reproduce, it's preferable to get detailed steps :)

Marco, is still a problem?

No, this dialog has completely been changed, so it is no longer a valid bug.
