title: How to include custom doc-comment elements in Sandcastle Help File?
body: <p>In C# if I have a method that I add XML documenting, the following will be generated by default:</p>
  
  <pre><code>/// &lt;summary&gt;
  /// Does something
  /// &lt;/summary&gt;
  public string SomeValue { get; set; }
  </code></pre>
  
  <p>I want to add my own doc-comment as follows below which is just fine in VS.NET build:</p>
  
  <pre><code>/// &lt;summary&gt;
  /// 
  /// &lt;/summary&gt;
  /// &lt;usage&gt;Required&lt;/usage&gt;
  public string SomeValue { get; set; }
  </code></pre>
  
  <p>The problem is I do not see the new <code>&lt;usage&gt;</code> comment values displayed on my output <code>.chm</code> file. I'm pretty new to using Sandcastle so it might be something easy I'm missing, but I didn't see what I was looking for in the documentation. </p>
  
  <p>Does anyone know how to incorporate the <code>&lt;usage&gt;</code> value in my output help file?</p>
