DDL dictionary version 2.1.3

_item_type_conditions.code

Name:
'_item_type_conditions.code'

Definition:

   
     Codes defining conditions on the _item_type.code specification.

     'esd' permits a number string to contain an appended standard
       deviation number enclosed within parentheses, e.g. 4.37(5)

     'seq' permits data to be declared as a sequence of values
       separated by a comma <,> or a colon <:>.
       * The sequence v1,v2,v3,. signals that v1, v2, v3, etc.
         are alternative values or the data item.
       * The sequence v1:v2 signals that v1 and v2 are the boundary
         values of a continuous range of values. This mechanism
         was used to specify permitted ranges of an item in
         previous DDL versions.
      Combinations of alternate and range sequences are permitted.
