title: nav element with no heading -- document outline
body: <p>This question has to do with document outline structure as it relates to headers within the <code>&lt;nav&gt;</code> element. It is not a question about validation.</p>
  
  <p>When I validate one of the pages for my web app, and check the field that says "document outline" the outline includes this:</p>
  
  <blockquote>
    <p>[nav element with no heading]</p>
  </blockquote>
  
  <p>I don't want to add a heading to my nav element because it will seem extraneous, to the consumer of the app, in the context of my nav (it's a nav element for pagination of a sub-section of the page); but I do want to have a well structured document outline.</p>
  
  <p>So my question is multi-part: </p>
  
  <ul>
  <li>Why is the outline including this?</li>
  <li>What is the proper way to add a heading to a nav element?</li>
  <li>Is it necessary to add a heading to a nav element? because it doesn't seem like a common practice on most websites.</li>
  </ul>
