title: Validation error: ul not allowed as child of element span
body: <p>I do not understand why the WC3 validator is flagging this HTML as invalid, the error it reports back is...</p>
  
  <p>''Element ul not allowed as child of element span in this context. (Suppressing further errors from this subtree.)''</p>
  
  <p>I'm using HTML5, and this code is for breadcrumbs.</p>
  
  <pre><code>&lt;span class="bread"&gt;
      &lt;ul&gt;
          &lt;li&gt;&lt;a href="./index.php"&gt;HOME&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;ABOUT&lt;/li&gt;
      &lt;/ul&gt;
  &lt;/span&gt;
  </code></pre>
