Maintaining the files

At a user site, an administrator might set up a procedure for filtering map messages and notifying someone who can resolve problems, by e-mail or e-mail pager. This means that the error numbers and the meanings associated with the numbers must remain the same after the first release of a map.

You can change the text associated with an error number, but you should avoid changing the meaning of the text or reassigning error numbers. If you do change the meanings associated with error numbers, you should document the change and notify users of the map.
