IOW if the role does not map to "none" it should be focusable.

Hi, Rich–

Thanks for pulling this together.

I had a short conversation with Florian Rivoal (CCed), the editor of the
CSS-UI L4 spec, and we talked about focusability in CSS, including the
notion of a 'focusable' property (to reflect the existing state in CSS),
and about depth/nesting. He's agreed to join a future telcon with us to
help coordinate.

I propose that the implicit "semantic" mechanism for the focusability of
an element be the following:
* textual elements
* links (<a>)
* any element (including <g>) with a <title> or <desc> immediate child

We can also allow explicit focusability, but the default should just
fall out of the model.

Regarding the depth/nesting proposal, I'm fine with what you've written.
I do think we should emphasize that nested containers is the proper way
to do that; this could be either container elements like <g> or <svg>,
or some sort of virtual grouping that lets an author override/work
around the tree structure. Again, this should be a consequence of the
