title: Enums/Documentation with LESS Mixins
body: <p>I am creating a set of LESS mixins with Visual Studio/Web Essentials.</p>
  
  <p>Is it possible to write XML-type documentation for LESS mixins?  Or perhaps have an enum to limit the parameters that are input?</p>
  
  <p>For instance, with this mixin:</p>
  
  <pre><code>.background-clip(@value)
  {
      -webkit-background-clip: @value;
         -moz-background-clip: @value;
              background-clip: @value;
  }
  </code></pre>
  
  <p>It would be nice to have some documentation that describes the three possible values, just like when you are creating a normal CSS selector for background-clip - </p>
