WAI-ARIA and Pagination
If you’re using HTML5 &lt;nav&gt; element, it’s not necessary to apply a role of ‘navigation’ – certain HTML elements inherently pass their relevant roles to the accessibility API. If you were wrapping the navigation menu in a &lt;div&gt;, for example, then you’d need to apply a role of ‘navigation’.

Role="menubar" has been correctly applied to the &lt;ul&gt; element, as has role="menuitem" to the &lt;a&gt; tags. 

I would suggest applying a role="none" to each &lt;li&gt; element; otherwise this could confuse some users of assistive technologies since listitems and menuitems would be interspersed with each other.

Might be an idea to provide an aria-label to the &lt;ul&gt; with role="menubar"; used to help people understand the menu purpose and uniquely identify it from other menubars on the page.

Can also apply a tabindex="0" to first and last &lt;a&gt; elements – gives keyboard focus to link and makes a part of the tab order of the page. Alternatively, give a tabindex="-1" to make &lt;a&gt;s focusable but not part of the tab order of the page.
