Re: Generated CSS content and browser/assistive technology compatibility

That is correct, JAWS is doing its own HTML parsing, like in IE, and is
not using the info from the accessibility tree. Neither is Window-Eyes
if that still has any relevance.

Frustrating, I know, but from our end, there's nothing we could do
except cut all support for ISimpleDOM, but that would leave all JAWS
users in the dark for an indeterminable amount of time. ;)
