title: Can I reference multiple elements using aria-describedby?
body: <p>If I have two elements that together describe one element, can I use two ids on <code>aria-describedby</code> attribute like this?  </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="description-1"&gt;&lt;/div&gt;
  &lt;div id="description-2"&gt;&lt;/div&gt;
  &lt;div aria-describedby="description-1 description-2"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
