I have not needed the notification mechanisms yet so please correct

current method may be theoretically less correct (though that
depends on how you define the "focus" concept) it would seem to me
that it is more powerful then if there would be only notifications
if the menu itself changes. I mean, in the current situation it
should be relatively easy for the accessibility app to figure out
after a notification for a menu item focus change that the item
belongs to the same menu so that the "focused" menu has not really
changed. In the alternative situation knowing that the "focused"
menu changes is easier, but there will no longer be a way to get
notified if the "focused" menu item changed.
You are correct; in the current model, you can use the
FocusedUIElement notification to find out when the selected menu
item changes. If I were to change to only send the FocusedUIElement
notification when the menu changes, then there would be no way to
track the menu selection, unless we added some other notification.

Actually, the only notification that's currently sent when the
selected item changes _is_ the FocusedUIElementChanged notification.
So taking all things into account it would seem to me that from an
accessibility app point of view the current behavior of the
FocusedUIElement notification for menus is preferable to the proposed
change of just notifying when another menu is selected.
