>From `C-h f':
(define-error NAME MESSAGE &optional PARENT)
Define NAME as a new error signal.
MESSAGE is a string that will be output to the echo area if such an error
is signaled without being caught by a `condition-case'.
PARENT is either a signal or a list of signals from which it inherits.
Defaults to `error'.
No, MESSAGE is not necessarily a string. It is a required argument, but
the code explicitly makes use of the case where it is nil. And existing
code delivered with Emacs (e.g. bookmark.el) makes use of a nil MESSAGE.
That case should be documented.
The doc in the manual has the same bug (node Error Symbols). MESSAGE is
*not* necessarily a string.
