title: c# XML avoid html encode using XDocument
body: <p>After creating an xml file using XDocument I end up with:</p>
  
  <pre><code>&amp;lt;![CDATA[text]]&amp;gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&amp;lt;br /&amp;gt;
  </code></pre>
  
  <p>But I want to keep these as HTML, how do I stop this?</p>
