/*
  Most of these codes can refer to either a duration or to a time period.
  "CD", "D", and "WD" are exceptions.
  The EDIFACT description can usually be parsed to distinguish a meaning --
  a type of time period except for "D" day, "W" week, and "Y" year; in which
  case the reference is to a duration -- but that may be merely a result of 
  a style of writing.
