Good point Joseph. One of the things I have been wrestling with is the fact that what is being launched (if it is not a descendant - hence aria-activedescendant) is the fact that what gets launched must indeed be a modal window. 

This would get us away from having to apply aria-activedescendant on a combobox in these instances however it needs to be clear that if aria-controls is these are housed in modal windows that are controlled by combobox. 

I am seeing other use cases in IBM where even expandable landmarks are mad “modal”. I think we need to discuss modality in this scenario. Clearly aria-activedescendant will not work in these scenarios (pop up control) as it is not a descendant. This really is not any different that having a live region controlled by another part of the page. If it is not owned then the focus must be determined by the modal window or object with in the window/container. 

Another option is to place these things in a dialog box where the combobox launches a dialog box with objects within. The dialog box MUST be modal.
