The authors of the specification are defining a technical mechanism that could be used to link a producer and consumer. They are explicitly NOT defining how capabilities are defined on services and the specifics for that part of the problem. HTTP does NOT define an operational interface beyond the interface it provides to browsers. When considering system->system interfaces it most certainly does not provide the required information to make both systems understand the interaction. > > I am confused - why do not simply accept what that spec says?? Because the specification says nothing (unless I've missed the section) about the definition of capabilities or service but just provides another technical implementation approach for the execution context. > > Jan > > > > > > > ------------------------ Yahoo!
