I was referring to the focus model of descendant elements of the canvas, not pixel data in the bitmap. Currently descendant elements cannot receive focus because the elements are not rendered in any context, visual or otherwise. In order to make a "shadow DOM" accessible, this focus model will need to change for all modalities. Those elements will probably need to behave as if they were rendered but not visible.
