It should be possible to decorated Business Object Data Members with custom description, similar to FunctionAttribute and DescriptionAttribute for User functions, http://docs.telerik.com/reporting/expressions-user-functions#providing-metadata-for-functions

It would be very useful to see custom documentation about data source types and -members when configuring a new Object Datasource for the report - more than Method, Type and Assembly which is displayed today.
