+@appendix Standard Errors
+
+ Here is the complete list of the error symbols in standard Emacs,
+grouped by concept. The list includes each symbol's message (on the
+@code{error-message} property of the symbol), and a cross reference to a
+description of how the error can occur.
+
+ Each error symbol has an @code{error-conditions} property which is a
+list of symbols. Normally, this list includes the error symbol itself,
+and the symbol @code{error}. Occasionally it includes additional
+symbols, which are intermediate classifications, narrower than @code{error}
+but broader than a single error symbol. For example, all the errors
+in accessing files have the condition @code{file-error}.
+
+ As a special exception, the error symbol @code{quit} does not have the
+condition @code{error}, because quitting is not considered an error.
+
+ @xref{Errors}, for an explanation of how errors are generated and
+handled.
