[中文适用范围]： 本国际标准规定了ISO/IEC 22534中定义的应用会话服务的Web服务（在第5条款中以WSDL形式描述）和SOAP绑定（在第6条款中）。应用会话服务允许应用程序与服务端建立名为应用会话的关系。此处指定的Web服务允许服务请求方（ISO/IEC 22534中的应用程序）和服务提供方（ISO/IEC 22534中的服务端）创建和维护此类应用会话。本国际标准构建并导入了来自ISO/IEC 22534的XML模式定义。向服务提供方和请求方提供指定服务的WSDL描述的方法不在本国际标准范围内。通知WSDL定义了ApplicationSessionTerminated操作。该操作指定了服务请求方从服务提供方接收事件通知的一个输入消息。服务请求方还可以从使用本国际标准进行会话管理的其他Web服务（例如ECMA-348）接收事件通知。 [外文原描述]： ISO/IEC 25437:2012 specifies Web Services (in WSDL, in Clause 5) and SOAP bindings (in Clause 6) for the Application Session Services defined in 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 Requesters (Applications in ISO/IEC 22534) and Service Providers (Servers in ISO/IEC 22534) to create and maintain such Application Sessions. ISO/IEC 25437:2012 builds upon and imports the XML schema definitions from ISO/IEC 22534. The method of making the WSDL description of the specified services available to Service Provider and Requester is out of the scope of ISO/IEC 25437:2012. The Notification WSDL specifies the ApplicationSessionTerminated operation. The operation specifies one input message for the event notification that Service Requesters receive from the Service Provider. Service Requesters may also receive the event notifications from web services, e.g. ECMA-348, that use ISO/IEC 25437:2012 for session management.
