Item _item_related.function_code


Description 


     The code for the type of relationship of the item identified by
     _item_related.name and the defined item.

      ALTERNATE  indicates that the item identified in 
      _item_related.related_name is an alternative expression in terms 
      of its application and attributes to the item in this definition.

      ALTERNATE_EXCLUSIVE indicates that the item identified in 
      _item_related.related_name is an alternative expression in terms
      of its application and attributes to the item in this definition.
      Only one of the alternative forms may be specified.

      CONVENTION  indicates that the item identified in 
      _item_related.related_name differs from the defined item only
      in terms of a convention in its expression.

      CONVERSION_CONSTANT indicates that the item identified in 
      _item_related.related_name differs from the defined item only
      by a known constant.

      CONVERSION_ARBITRARY indicates that the item identified in 
      _item_related.related_name differs from the defined item only
      by a arbitrary constant.

      REPLACES  indicates that the defined item replaces the item identified 
      in _item_related.related_name.

      REPLACEDBY  indicates that the defined item is replaced by the
      item identified in  _item_related.related_name.

      ASSOCIATED_VALUE indicates that the item identified in 
      _item_related.related_name is meaningful when associated with the
      defined item.  

      ASSOCIATED_ESD indicates that the item identified in 
      _item_related.related_name is the estimated standard deviation of
      of the defined item.
