    description     
     "An octet string containing a list of item values.
      
      An item value is an arbitrary string of octets from
      ASCII character 0x30 - 0x39, but may not contain 
      a delimiter character. Delimiter characters are 
      defined to be one of the following:
      
          -  An ASCII comma character (0x2C)
          -  An ASCII colon character (0x3A)
      
      Delimiter characters are used to separate item values
      in a item list.  Only a single delimiter character may
      occur between two item values.  A item value may not
      have a zero length.  These constraints imply certain
      restrictions on the contents of this object:
      
          - There cannot be a leading or trailing delimiter
            character.
      
          - There cannot be multiple adjacent delimiter
            characters.
      
      The 'comma' delimiter separates individual items or a
      sequence of items. The 'colon' delimiter indicates a range
      of items from the first item before the colon through the
      last item after the colon. Individual ranges in the same
      item list need to be separated by a 'comma'.
      
      Some examples of valid item lists are:
      
          - ''            -- an empty list
          - '1234'        -- list of one item
          - '10,11,12'    -- list of several items
          - '10:20'       -- a list containing all the valid values from
                             10 through 20
      
      Note that although an item value may not have a length of
      zero, an empty string is still valid.  This indicates
      an empty list (i.e. there are no tag values in the list).
      
      The use of the item list is to select one or more items at
      one time with a single object instead of having separate row
      entries in a table for each individual item.";
