       * This will create a formatter with the {@linkplain Locale#getDefault(Locale.Category) default FORMAT locale}.
       * Numbers will be printed and parsed using the standard DecimalStyle.
       * The resolver style will be {@link ResolverStyle#SMART SMART}.

-      * the chronology and/or the zone are overridden. If both "ca" and "rg" are

-      * from the "rg" extension.

       * Calling this method will end any open optional sections by repeatedly
       * calling {@link #optionalEnd()} before creating the formatter.
