 /**
  * 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.
