title: Html5 attributes for side menu
body: <p>I have a page with the usual suspects on - header, main nav etc.</p>
  
  <p>In the main page I have an article such as terms &amp; conditions, then in the left column an associated menu that can be used to switch between different policies - privacy, cookie policy etc.</p>
  
  <p>From what I've read this is not a use for the nav attrcibute (I could be wrong), but is it then an aside as it does relate to the main content of the page?</p>
  
  <p>Any advice appreciated.</p>
