This is a test of a static menu on a web page, in which one of the items is currently selected. The problem we're trying to solve is this: How do we communicate to screen reader users that an item has been selected? The aria-selected attribute would seem to be the appropriate attribute, but it isn't valid on just any element. The only applicable role is tab, so that would seem to dictate our using role="tab" (and related roles) for the menu.
