+// In locales that don't have a relative-date/time formatter -- and presently
+// "ak" is such a locale -- behavior is expected to fall back to the root-locale
+// formatter.  This test verifies such fallback works as long as "ak" satisfies
+// these properties; "ak" may safely be changed to a different locale if that
+// ever changes.  See bug 1504656.
