   --  and stores the result in Buf, setting Buflen to the number of stored
   --  characters (Buf has a lower bound of 1). If more than Buflen characters
   --  are present in the literal, Data_Error is raised.

      Stop  : out Natural);
   --  Scans an enumeration literal at the start of From, skipping any leading
   --  spaces. Sets Start to the first character, Stop to the last character.
   --  Raises End_Error if no enumeration literal is found.

      Item  : Wide_String;
