But I don't understand, what do you mean by "not interoperable"?
thanks
Interopearability in the sense of communicating
soap messages between various platform like php,
java, .net etc.,
If you use the primitive data types(like int, byte,
string, char) then most the serialization process is taken care by sofware solution provider itself(for example axis, .netframework). For other types you have explicitly configure your applicaiton in the deployment descriptor and so on.
