Text mode except that it provides two additional commands. Its
definition is distinct from that of Text mode, but uses that of Text mode.
+ Even if the new mode is not an obvious derivative of any other mode,
+it can be convenient to define it as a derivative of
+@code{fundamental-mode}, so that @code{define-derived-mode} can
+automatically enforce the most important coding conventions for you.

Rmail Edit mode offers an example of changing the major mode
temporarily for a buffer, so it can be edited in a different way (with
ordinary Emacs commands rather than Rmail commands). In such cases, the
mode specification error}, followed by the original error message.
