-It's generally not a good idea to put the `edittemplate` directive in
-the template page itself, since the directive would then be included as
-part of the template on new pages, which would then in turn be registered
-as templates. If multiple pages are registered as templates for a new page,
-an arbitrary one is chosen, so that could get confusing.
+If the template does not contain a [[templatebody]] directive, the entire
+source of the page is used for the template. This is deprecated.
