    84 ==== !MgDecimalProperty ====
    85 
    86 Many FDO data sources support decimal type property. So users can create a decimal property in those datasources. However, MapGuide Web API doesn't have a decimal property class. Decimal value is returned as double value.

     109==== Changes to !MgPropertyType ====
     110
     111Many FDO data sources support decimal type property. 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.
