As an example, Inclusive Components Tabbed Interfaces starts with a Table of Contents marked up as an unordered list of links. However in enhanced mode the links take on a new role as tabs in a
role=presentation is applied to their containing
<li> elements so that the tab list is announced appropriately and not as a plain list.
