         This section specifies the template justification.
         
      
      
         NOTE 
         The template has been defined in the context of 
         UK_Defence.
         Refer to the business context for details of related templates.
         
      
      
         NOTE 
         An explanation of a template and the associated instantiation path is
         provided in the 
         Template overview
         section.
         
      
      
      
               
         This template describes how to represent the UK_Defence concept of a Justification in terms of PLCS model elements (templates,
            entities, and reference data).

         Justification:
               
         The definition of a Justification is:
                    This information object represents a justification for a decision or for something having been done.
                  
         
               
         
                    The item that is justified is defined by whatever references this object.

            template (justification) namely: 
            
ID,
            
a_justification_for.
The 
            
            instance is
            
            referenced by the following template parameter:

         The instantiation path shown below specifies the entities that are to be
         instantiated by the template.
         
      
      
         A description of templates and the syntax for the instantiation path is

         shows the graphic symbol for the template that is to be

Characterizations
      
         No common characterizations of the template 
         justification
         have been identified. However, the ISO 10303-239 EXPRESS model
         may enable other assignments to the entities instantiated by the template.
