Hi

I am sorry , was just going through the emails, and actually not
formally a part of this group.But,

I dont think a Web Service should have only 1 interface, although it seems
so.
But deep inside a core web service can /should have more than 1 interfaces
if the "core service has a interface", but the multiple interfaces extend
this core service
interface depending on the context of the invoker(s) of this web service.

I am not sure if my reply is relevant,but anyway thats my 2 cents.
