title: How do I force document comment
body: <p>I have a SDK that few developers can edit and add new methods.
  I want to force each developer that adds a new function to add documented comment.
  the documented comment should include the supported version of this method.
  for the summary I added XML documentation file and it works for me (the build fails if no documented comment)
  I still have no solution for the supported version comment</p>
  
  <pre><code>    /// &lt;summary&gt;
      /// Function1 description
      /// &lt;/summary&gt;
      /// &lt;**supportedSince**&gt;Version 5.6&lt;/**supportedSince**&gt;
      public List&lt;string&gt; Function1{ get; set; }
  </code></pre>
