Hey.

ARIA has aria-setsize="-1" to point out that a set of items has unknown
size [1]. ATK uses ATK_STATE_INDETERMINATE [2], which also used for
tri-state checkboxes.

So do we want to IA2-extend MSAA's SYSTEM_STATE_MIXED, used for tri-state
checkboxes, to this case? Should we go with a new IA2's INDETERMINATE state?

Thanks!
Alexander.

Hi.
I don't think we need a state for this. IAccessible2::groupPosition already
exists and it doesn't define meanings for -1, so I think we could just
return similarItemsInGroup as -1.

Sounds good with me. Thanks! I'll come back with this accord to ARIA group.
