+/**
+ * DateFormatSymbols is a public class for encapsulating localizable date-time
+ * formatting data -- including timezone data. DateFormatSymbols is used by
+ * DateFormat and SimpleDateFormat.
+ * <P>
+ * Rather than first creating a DateFormatSymbols to get a date-time formatter
+ * by using a SimpleDateFormat constructor, clients are encouraged to create a
+ * date-time formatter using the getTimeInstance(), getDateInstance(), or
+ * getDateTimeInstance() method in DateFormat. Each of these methods can return a
+ * date/time formatter initialized with a default format pattern along with the
+ * date-time formatting data for a given or default locale. After a formatter is
+ * created, clients may modify the format pattern using the setPattern function
+ * as so desired. For more information on using these formatter factory
+ * functions, see DateFormat.
+ * <P>
+ * If clients decide to create a date-time formatter with a particular format
+ * pattern and locale, they can do so with new SimpleDateFormat(aPattern,
+ * new DateFormatSymbols(aLocale)).  This will load the appropriate date-time
+ * formatting data from the locale.
+ * <P>
+ * DateFormatSymbols objects are clonable. When clients obtain a
+ * DateFormatSymbols object, they can feel free to modify the date-time
+ * formatting data as necessary. For instance, clients can
+ * replace the localized date-time format pattern characters with the ones that
+ * they feel easy to remember. Or they can change the representative cities
+ * originally picked by default to using their favorite ones.
+ * <P>
+ * DateFormatSymbols are not expected to be subclassed. Data for a calendar is
+ * loaded out of resource bundles.  The 'type' parameter indicates the type of
+ * calendar, for example, "gregorian" or "japanese".  If the type is not gregorian
+ * (or NULL, or an empty string) then the type is appended to the resource name,
+ * for example,  'Eras_japanese' instead of 'Eras'.   If the resource 'Eras_japanese' did
+ * not exist (even in root), then this class will fall back to just 'Eras', that is,
+ * Gregorian data.  Therefore, the calendar implementor MUST ensure that the root
+ * locale at least contains any resources that are to be particularized for the
+ * calendar type.
