 * This holds onto information about how a particular locale formats dates. It
 * contains mostly strings, e.g. what the names of months or weekdays are,
 * but also indicates things like the first day of the week. We expect the data
 * for instances of these to be generated out of ICU or a similar reference
 * source. This is used in conjunction with the date_time_patterns, which
 * defines for a particular locale the different named formats that will
 * make use of this data.
