/**
 * Value type that represents a date in the ISO-8601 calendar.
 * There is no representation of time-of-day or time-zone.
 *
 * <blockquote>
 * The “local” terminology is familiar from Joda-Time and comes originally from the ISO-8601 date and time standard.
 * It relates specifically to the absence of a time-zone. In effect, a local date is a description of a date,
 * such as the “5th April 2014”. That particular local date will start at different points on the time-line
 * depending on where on the Earth you are. Thus the local date will start in Australia 10 hours before it
 * starts in London and 18 hours before it starts in San Francisco. -- Stephen Colebourn in
