This question would probably be good to ask on the public WAI list, since it
relates to W3C documentation. I suspect the tabindex=0 scenario was added to
account for a dialog that has no other active elements within it, but this
shouldn't be the case in practice for any situation I can think of.

Thanks everyone for this helpful discussion.

Any thoughts on why the ARIA Authoring practices guide suggests tabindex=0
on the document content area of an alertdialog? If there is nothing to
interact with, why set tabindex to 0?

http://www.w3.org/TR/wai-aria-practices/#alertdialog

It's in the WAI-ARIA Roles, States, and Properties cell.

Thanks again,
Jesse
