标准摘要
[中文适用范围]： 本推荐实践定义了SLE API的扩展，包括：a) API组件提供的CLTU特定功能；b) API组件提供的CLTU特定接口；c) 组件导出的CLTU接口的外部可见行为。 它不规定：a) 个别实现或产品；b) 组件的内部设计；c) 用于通信的技术。 本推荐实践仅定义必须由支持前向CLTU服务的实现提供的接口和行为，除了参考[5]中的规范。 [外文原描述]： ISO 18445:2016 Practice defines extensions to the SLE API in terms of: a) the CLTU-specific functionality provided by API components; b) the CLTU-specific interfaces provided by API components; and c) the externally visible behavior associated with the CLTU interfaces exported by the components. It does not specify a) individual implementations or products; b) the internal design of the components; and c) the technology used for communications. ISO 18445:2016 defines only interfaces and behavior that must be provided by implementations supporting the forward CLTU service in addition to the specification in reference [5].
