title: Nesting a ul inside an ol
body: <p>Im trying to make an ordered list with two items, and three items under each list, which have bullet points. my code is not passing validation because it saysElement ul not allowed as child of element ol in this context. But everywhere I look it says this is ok. here is my code</p>
  
  <pre><code>&lt;ol&gt;
      &lt;li&gt;First numbered Item&lt;/li&gt;
          &lt;ul&gt;
              &lt;li&gt;one thing&lt;/li&gt;
              &lt;li&gt;two things&lt;/li&gt;
              &lt;li&gt;three things&lt;/li&gt;
          &lt;/ul&gt;
      &lt;li&gt;Second numbered Item&lt;/li&gt;
          &lt;ul&gt;
              &lt;li&gt;one thing&lt;/li&gt;
              &lt;li&gt;two things&lt;/li&gt;
              &lt;li&gt;Three things&lt;/li&gt;
          &lt;/ul&gt;
  &lt;/ol&gt;
