WSDL (Web Services Description Language) describes service operations, bindings, and endpoints. SOAP encoding rules define how types map to XML. WS-Security adds message-level encryption and signatures. WS-Addressing provides message routing metadata. WS-ReliableMessaging ensures delivery guarantees. The WS-* stack provides enterprise features but adds complexity. SOAP is used in legacy enterprise and financial systems.
