scope:

This International Standard specifies Web Services (in WSDL) and a SOAP binding for the Application Session Services defined in (ECMA 354) ISO/IEC 22534. The Application Session Services allow Applications to create and maintain a relationship with Servers termed Application Session. The Web services specified herein, allow Service Subscribers (Applications in (ECMA 354) ISO/IEC 22534) and Service Providers (Servers in (ECMA 354) ISO/IEC 22534) to create and maintain such Application Sessions. This International Standard builds upon and imports the XML schema definitions from (ECMA 354) ISO/IEC 22534. Although this International Standard only specifies the abstract WSDL definitions and its SOAP binding, Annex A shows an example WSDL binding with SOAP/HTTP. Annex B lists SOAP XML Templates for (ECMA 354) ISO/IEC 22534 Messages. Annex C illustrates how WS-Eventing can be used to establish event channels to receive ApplicationSessionTerminated messages.
