title: Cannot add role="navigation" to wp_nav_menu()
body: <p>I would like my custom nav menu to have an attribute "role" with value of "navigation". It does not appear that wp_nav_menu() accepts an attributes argument. Am I missing something?</p>
  
  <pre><code>&lt;nav role="navigation"&gt;...&lt;/nav&gt;
  </code></pre>
