   <td>If the document is an {{HTMLElement("iframe")}} {{htmlattrxref("srcdoc", "iframe")}} document, or if title information is available from a higher level protocol, zero or more elements of metadata content.<br>
    Otherwise, one or more elements of metadata content where exactly one is a {{HTMLElement("title")}} element.</td>

<h2 id="Notas">Notas</h2>

<p>Modern, HTML5-compliant browsers automatically construct a <code>&lt;head&gt;</code> element if the tags are omitted in the markup. <a class="external" href="https://www.stevesouders.com/blog/2010/05/12/autohead-my-first-browserscope-user-test/">This behavior cannot be guaranteed in ancient browsers</a>.</p>
