Rich, Matt,

(Sorry for the double post, but I forgot to include the public aria list 
last time.)

I had an action to modify the definition for aria-activedescendant in 
light of the changes to combobox.  The changes were made in this branch:
http://rawgit.com/w3c/aria/mck-action1490-activedescendant/aria/aria.html#aria-activedescendant

I added a paragraph to the end of the definition:

"
A special use case is a combobox where its textbox has DOM focus, and 
that textbox employs an aria-activedescendant attribute to reference the 
currently active listbox option. The referenced listbox option is not in 
fact a descendant of the textbox itself, but of its parent combobox 
element. Even so, the aria-activedescendant property is treated by user 
agents as the active descendant of the combobox, and not the textbox.
"
