Rich is asking for a clarification in the UAIG that the inner element should still be exposed in the accessibility tree. Do you agree with what he is proposing?

I don't agree that the element should be exposed. If the ancestor is hidden, all descendants should also be hidden. If the same way, if you have CSS display:none on a node, adding display:block to a child element does not make it appear.

Another technical challenge regarding the AX tree would be that you'd have to promote these child nodes to a higher branch, since the parent element is no longer in the tree. This could result in very unexpected behavior in some APIs.
