SDL
规范说明和描述语言SDL SDL是一种应用较广的形式化描述语言，由原CCITT(国际电报电话咨询委员会）现ITU-T(国际电信联盟电信标准局）制定，在ITU-T Z.100建议中给出了SDL的完整定义。 The purpose of recommending SDL (Specification and Description Language) is to provide a language for unambiguous specification and description of the behaviour of telecommunication systems. The specifications and descriptions using SDL are intended to be formal in the sense that it is possible to analyse and interpret them unambiguously.
