It's not a client app which notifies accessibility explicitly, but I tried
my app with sample Cocoa app without any explicit notification (according to
doc, all notifications by default should be handled for standard
system-defined user interface in Cocoa app unless we use our own interface.
Or am I missing something here). One other thing I tried was the Universal
Access panel which clearly shows accessibility notification which is
captured by text-to-voice assistive module reading the text under mouse. I
assume here that the assistive module is an external app, though.
Thank you for the reply.

The Accessibility API is implemented for Carbon. However, you won't
necessarily receive these events on the application target; it depends
on what other apps are requesting. Do you have an accessibility client
app (one that uses the Accessibility API to inspect other apps) that
you're using to test your own accessibility handlers?
