ARIA Presentation Role
The ARIA role="presentation" is used to obscure the structure of the element which contains the role but does not obscure the content of the element. When the role is applied to structures like lists that have related child elements like list items that effect of role of presentation applies to these child items too. Other child items that are not directly controlled by the list such as links would not have their role obscured. Interactive elements should not have a role of presentation.
Applying other roles such as "navigation" to a "ul" element does not change the semantics of the children element like role of presentation does and may leave orphaned li elements.
