1 This part of ISO/IEC 9594 defines a number of attribute types which may be found useful across a range of applications of the Directory.
2 Attribute types (and attribute syntaxes) fall into three categories, as described in 1.2.1 through 1.2.3.
1.1 Some 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 Some attribute types (syntaxes) are internationally-standardized, but are application-specific. These are defined in the standards associated with the application concerned.
1.3 Any administrative authority can define its own attribute types (syntaxes) for any purpose. These are not internationally standardized, and are available to others beyond the administrative authority which created them only by bilateral agreement.
