. If the
field has a datePatternStrict variable, that will be used to format java.text.SimpleDateFormat
and the length will be checked so '2/12/1999' will not pass validation with
the format 'MM/dd/yyyy' because the month isn't two digits. If no datePattern
variable is specified, then the field gets the DateFormat.SHORT format for
the locale. The setLenient method is set to false
for all variations.
