This clause specifies the information requirements for the Justification application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
The following EXPRESS specification begins the Justification schema.
EXPRESS specification:
*)
SCHEMA Justification_arm;
(*
This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.
The justification_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the justification_item type.
NOTE This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.
EXPRESS specification:
*)
TYPE
justification_item =
EXTENSIBLE
GENERIC_ENTITY
SELECT;
END_TYPE;
(*
The justification_support_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the justification_support_item type.
NOTE This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

(*
This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.
EXAMPLE A justification may be provided for a product design. Similarly, a justification may be provided for why an activity is needed or was undertaken.
