If you create an issue it would be interesting to see what replies from Engineering it gets.
I faintly remember using these interfaces back in the REALbasic days when we could create our own bindings but that is gone now and I wonder if the interfaces need updating and also the documentation.
The ActionNotificationReceiver seems to work for DeskTopButton ActionNotificationReciever
And that is how we used to use binding to a listbox with ListSelectionNotificationReceiver
