I want to use English and Persian Comments, both. But in tool-tip I will see just ///Summary content. So, the question is that:  
- Is that possible to see comments in tool-tip in both languages?
 If It's not possible, which documentation is recommended? use standard language in summery or localizing that? (for show in tool-tip). Which one is better:
/// <summary> /// Gets All objects of type .... /// </summary> /// <summary xml:lang="fa"> /// تمام موجودیت ها از نوع ... را برمیگرداند /// </summary> /// <returns>All Objects of type .... </returns> IEnumerable<T> GetAll();
or:
        /// <summary>
        /// تمام موجودیت ها از نوع ... را برمیگرداند
        /// </summary>
        /// <EN>Get The object of type ... </EN>
        ....  
- If it's better to use localized commenting, can I set it as Right-to-Left?!
