In response to a discussion on another mailing list, I tested Orca 2.30.2 and Firefox 3.6.10 (Debian Iceweasel package from Experimental) with the following test page (thanks to Leif Halvard Silli): http://malform.no/testing/longdesc/img longdesc html Orca didn't seem to recognize the LONGDESC attribute. To find out whether the presence of the attribute was actually being disclosed in the accessibility API events, I obtained debug logs. While not being an expert in reading these, I didn't find anything that seemed to correspond to the LONGDESC attribute. On the other hand, the logs tend to be lengthy. Sample logs are attached. This could well be a Mozilla issue rather tahn an Orca one.
