-==== Changes to !MgPropertyType ====
-
-Many FDO data sources support decimal property type. Users can add a decimal property in a feature class in those datasources. However, class !MgPropertyType doesn't define a decimal property type. So we will extend class !MgPropertyType to add a new type name 'Decimal' so that method MgFeatureService::!ApplySchema(...) can handle the decimal property.

 This is new API only. There will be no effect on existing applications. However, API documentation need to be updated.
 
-Currently, there is no enough resources and funding to support creating non-file based feature source. They may be implemented if resources and funding can be obtained in the future.
