Q63. Given the Java fragment and schema:
1. //-- Java code fragment
2. public enum USState {MA, NH}
3. //-- Schema fragment
4. <xs:simpleType name=xsState?
5. <xs:restriction base=xs:string?
6. <xs:enumeration value=NH?/>
7. <xs:enumeration value=MA?/>
8. </xs:restriction>
9. </xs:simpleType>
10. // .NET auto generated code from schema
11. public enum usState { NH, MA }
Which statement is true about .Net and WCF interoperability for this data?
A. Based on the fragment, enumerations map well between Java and .Net.
B. The subtle differences in the variable names make it clear these enumerations are NOT interoperable.
C. The XML schema reveals the type on the enumeration is lost across the platforms.
D. This exchange would be interoperable if the annotation @XmlEnum was applied to the Java method.
