title: HTML5 block-quote with author
body: <p>Hi I'm seeing a great number of different ways to implementat <code>blockquote</code> in html but it doesn't seem clear in its documentation how should I properly format a <code>blockquote</code> <em>let's say</em> of a famous quote and metion its author like:</p>
  <blockquote>
  <p>In victory, you deserve Champagne, in defeat, you need it.</p>
  <p>Napoleon Bonaparte</p>
  </blockquote>
  <p>What would the correct format of that be in HTML5?</p>
  <p>Should the author be inside or outside the <code>blockquote</code> tag?
  Should it be inside the <code>cite</code> attribute? (even knowing the documentation specifies an URI , not author)</p>
