+      
+      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.";
