ARIA role=tree for mobile?

I'm specifying requirements for a mobile-only navigation that has more than one level. I know it should be coded as a nested unordered list. What I don't know if VoiceOver and TalkBack support aria role="tree" and role="treeitem."

On an iPhone5, I was trying out this example, linked from the WAI page http://oaa-accessibility.org/examplep/treeview1/

There was no indication of any structure or whether the tree was expanded or collapsed. Nor was there any indication when I was on the first or last item in a list, which I typically hear in an unordered list.

It seems like the ARIA in this case got in the way of the list structure. My gut is not to use it for a mobile-only implementation.

Would love thoughts from anyone who can chime in.


Best,
