使用Microsoft.AspNet.WebApi.HelpPage添加JSON示例

Question

我已经使用Microsoft.AspNet.WebApi.HelpPage和C＃XML注释为我的Web API项目生成Web API文档，但是想要为每个方法添加JSON示例，并且无法弄清楚如何。

这是我方法的XML评论：

        /// <summary>
        /// Gets data values for a given data key.
        /// </summary>
        /// <param name="masterAgencyID">The MasterAgencyDivisionID for the desired values.</param>
        /// <param name="masterClientID">The MasterClientID for the desired values.</param>
        /// <param name="dataKeyCode">The DataKey's code for which values are to be returned.</param>
        /// <returns>An object containing two lists: IncludedValues and ExcludedValues.</returns>
        /// <example>
        /// {
        ///     "IncludedValues": [
        ///         {
        ///             "DataValueID": 644,
        ///             "DataValueCode": "1000X500",
        ///             "DataValueShortDescr": "1000X500",
        ///             "excluded": false
        ///         },
        ///         ...
        ///     ],
        ///     "ExcludedValues": [
        ///         {
        ///             "DataValueID": 644,
        ///             "DataValueCode": "1000X500",
        ///             "DataValueShortDescr": "1000X500",
        ///             "excluded": true
        ///         },
        ///         ...
        ///     ]   
        /// </example>

以下是该方法生成的网页：

如您所见，在“示例：”下，页面显示“示例不可用”。

显然不是从XML标签中读取。如何在API文档中包含示例？
