Criterion 9.3 – Appropriate structured list

This post is also available in: Français (French)

The WAI-ARIA Roles list and listitem may require the use of the aria-setsize and aria-posinset properties, if the entire list is not available via the DOM generated at the time of rendering.

Despite the existence of the definition role, used in combination with the aria-labelledby property, WAI-ARIA does not offer a role equivalent to HTML definition lists (DL). The definition role can not, therefore, be used as an equivalent of an HTML definition list DL.

The roles tree, tablist, menu, combobox and listbox are not equivalent to an HTML ul or ol list.
