In that case, I don't see how we can do much.  A system that can't
return non-fatal errors to the application and can't display them to
the user just has no way to signal non-fatal errors.  And I don't
think that this should result in standards only being able to require
errors to be reported if they are fatal.  So I think you will just
have to be non-conformant in this respect.
