hello group: The following is a fragment from a schema which defines the EWethnicCategoryStructure type. As you can see, its type is defined by the SimpleType enumeration EWethnicCategoryType. EWethnicCategoryType is defined as a union with the CommonEthnicCategoryType SimpleType enumeration. Now when I use the XSD tool to create a C# class of this schema, the resulting code does not include the SelectedEthnicCategory enumeration.
