/// There is no validity flag for ‘year’, since it must always be by definition mandatory in order to have a sensible date/time at all. Syntax expressions of instances of this class include “YYYY-MM-DDT??:??:??” (date/time with optional time) and “YYYY-MMDDTHH:MM:xx” (date/time, seconds not allowed).
