Class C_DATE

ISO 8601-compatible constraint on instances of Date in the form either of a set of
validity values, or an actual date range. There is no validity flag for year', since it
must always be by definition mandatory in order to have a sensible date at all.
Syntax expressions of instances of this class include YYYY-??-?? (date with
optional month and day).
Date ranges are probably only useful for historical dates.
