+  Class create localized_text -superclass text -ad_doc {
+
+    This class can be used to provide an interface for specifying
+    internationalized text strings saved in message keys via input
+    from a form. When editing the content provided via the input field
+    is saved together with an item-specific message keys in the
+    message key tables via lang::util::convert_to_i18n.
+
+    This formfield class is especially useful for xowiki items which
+    have no language-prefix (e.g. folders or links). In other cases it
+    is probably still a better idea to create same named pages with
+    different language prefixes.
