I've just installed the plugin blogged about by Mike Ormond and here's an example of it's output taken from code in the Atrax project I've just published to Codeplex.

namespace Atrax.Library
{
   [DataContract, Serializable]
   public class QueryResult
   {
      /// <summary>
      /// The original query sent by the client.
      /// </summary>
      [DataMember]
      public Query Query { get; set; }

      /// <summary>
      /// Status code sent back to query client's callback url.
      /// </summary>
      [DataMember]
      public string StatusCode { get; set; }
      
      /// <summary>
      /// Status description sent back to query client's callback url.
      /// </summary>
      [DataMember]
      public string StatusDescription { get; set; }
      
      /// <summary>
      /// The XML schema for the result XML.
      /// </summary>
      [DataMember]
      public string ResultSchema { get; set; }

      /// <summary>
      /// The result produced by the query processor, usually XML.
      /// </summary>
      [DataMember]
      public string Result { get; set; }
   }
}
