   Re: [xml-dev] Demand for web services

[ Lists Home | Date Index | Thread Index ]

I'm with Jim. The primary driver behind (first) XML-RPC and (second)

make heterogeneous systems interoperate. It's about separation of
concerns at the middleware level (platform/language/infrastructure),
not at the presentation level.
