Thank you for your reply.
I have understood the WG solution for my question.
However, please allow me to ask one more question I face.
I think "<choice>" solution  is very smart, but I'm afraid of the case 
that an interface extends the other interface, and an operation of the 
extened interface is required to add (or change) inputs which the super 
interface doesn't have.

In WSDL 1.2 concept, in this case, should we define the different 
operation though the original operation and re-difined one are same 
semantically? Or have you disucussed a solution?
