title: Nesting h3 inside anchor - how is this valid?
body: <pre><code>&lt;li class="vcard"&gt;
    &lt;a class="url" href="/about/us/"&gt;
      &lt;img class="photo" alt="some" src="/img/nicething.png"&gt;
      &lt;h3&gt;hello&lt;/h3&gt;
    &lt;/a&gt;
    &lt;p class="role meta"&gt;Something here&lt;/p&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>I've seen this code, I've validated and it returns VALID on w3c HTML5 validation.</p>
  
  <p>I tough that we couldn't have <code>h3</code> inside an <code>anchor</code>.</p>
  
  <p>It seems that this became valid if we <code>display:block;</code> the anchor ?</p>
