...(if I recall correctly) uniqueID is only unique within a given hwnd.
The spec says:
The uniqueID is an identifier for this object, is unique within the
current
window, and remains the same for the lifetime of the accessible object.
The uniqueID is not related to the MSAA objectID which is used by the
server
to disambiguate between IAccessibles per HWND or the MSAA childID which is
used to disambiguate between children being managed by an IAccessible.
I don't remember a discussion about uniqueID being unique per each HWND.
Perhaps the wording "unique within the current window" could be improved.
Does anyone have a suggestion?
Also what assumption have people already made about uniqueIDs?

text was that it would be unique within a frame, e.g. a single app might
be able to activate more than one client area wrapped with some chrome,

the perspective of the app developer, what is the largest scope within
which uniqueness could be managed? And how would you describe that
environment?</font>

Is there a bug filed for that?<br>
<br>
As far as I know, if several accessible objects share the same DOM node,
we use a different pointer (from the internal accessible object itself),
thus avoiding any issues.<br>
<br>
So, unless you know of particular issues, I think we're fine.<br>

it's Firefox bug I think.<br>
