1范围1。1 ISO/IEC 9594的这一部分定义了许多属性类型，这些属性类型可能在目录的一系列应用程序中都很有用。1.2属性类型（和属性语法）分为三类，如1.2.1至1.2.3.1.2.1所述，一些属性类型（语法）被各种应用程序使用，或者被目录本身理解和/或使用。注意——建议使用本文档中定义的属性类型（语法），而不是生成新的属性类型，只要它适合应用程序。1.2.2一些属性类型（语法）是国际标准化的，但不适用于应用程序- 具体的这些在与相关应用相关的标准中定义。1.2.3任何管理机构都可以出于任何目的定义自己的属性类型（语法）。这些文件没有国际标准化，只有通过双边协议才能提供给创建这些文件的行政当局以外的其他人。

1Scope1.1This part of ISO/IEC 9594 defines a number of attribute types which may be found useful across a range of applications of the Directory.1.2Attribute types (and attribute syntaxes) fall into three categories, as described in 1.2.1 through 1.2.3.1.2.1Some attribute types (syntaxes) are used by a wide variety of applications or are understood and/or used by the Directory itself.NOTE - It is recommended that an attribute type (syntax) defined in this document be used, in preference to the generation of a new one, whenever it is appropriate for the application.1.2.2Some attribute types (syntaxes) are internationally standardized, but are application-specific. These are defined in the standards associated with the application concerned.1.2.3Any administrative authority can define its own attribute types (syntaxes) for any purpose. These are not internationally st andardized, and are available to others beyond the administrative authority which created them only by bilateral agreement.
