Some prior art re diagnostics detection and handling

[MURATA Makoto]

Here is what XML (fifth edition) says.

error
[Definition: A violation of the rules of this specification; results
are undefined.
Unless otherwise specified, failure to observe a prescription of this
specification
indicated by one of the keywords must, required, must not, shall and shall not
is an error. Conforming software may detect and report an error and
may recover from it.]

fatal error
[Definition: An error which a conforming XML processor must detect
and report to the application. After encountering a fatal error, the processor
may continue processing the data to search for further errors and may
report such errors to the application. In order to support correction
of errors, the processor may make unprocessed data from the document
(with intermingled character data and markup) available to the application.
Once a fatal error is detected, however, the processor must not continue
normal processing (i.e., it must not continue to pass character data and
information about the document's logical structure to the application in
the normal way).]
