title: How do I tell doxygen to leave my XML comments alone?
body: <p>I have that <a href="http://www.doxygen.nl/manual/markdown.html#md_fenced" rel="nofollow noreferrer">fenced code block</a> with an XML fragment:</p>
  
  <pre class="lang-c prettyprint-override"><code>/**
   * ~~~~~~{.xml}
   * &lt;parent&gt;
   *   &lt;child&gt;&lt;/child&gt;
   *   &lt;!-- comment I want to see --&gt;
   * &lt;/parent&gt;
   * ~~~~~~
   */
  </code></pre>
  
  <p>The generated HTML documentation does no longer contain the comment:</p>
  
  <p><a href="https://i.stack.imgur.com/7vNou.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7vNou.png" alt="enter image description here"></a></p>
  
  <p>How do I tell doxygen that it shall keep the comment also in the generated docs?</p>
  
  <p>Comments in <code>C++</code> blocks are rendered properly, the issue is only with XML code.</p>
