title: XML-documentation for a namespace
body: <p>Would you write xml-doc for a namespace? And if yes, how and where?</p>
  
  <p>I would think, if it is possible, maybe an almost empty file like this:</p>
  
  <pre><code>/// &lt;summary&gt;
  /// This namespace contains stuff
  /// &lt;/summary&gt;
  namespace Some.Namespace
  {
  
  }
  </code></pre>
  
  <p>But will that work? Since you... "declare", or at least use the namespace in all the other files as well... and what would happen if you wrote an xml-documentation thing somewhere else on the same namespace? Would one be gone? Or would they be merged somehow?</p>
