+// This package is intended to be used by the table generation tools for the
+// various packages in x/text and is not internal for historical reasons.
+//
+// As the XML types are generated from the CLDR DTD, and as the CLDR standard is
+// periodically amended, this package may change considerably over time. This
+// mostly means that data may appear and disappear between versions. That is,
+// old code should keep compiling for newer versions, but data may have moved or
+// changed. CLDR version 22 is the first version supported by this package.
+// Older versions may not work.
