Stop right here.  It's rejected with a message.

To provide another voice on Andrew's side, tough, they're all broken.  The
AO record already protects itself against garbage input.  IMHO the GUI
should not be inserting junk into the system.  That's an input editing
function, for which the GUI already has the necessary information.

I'll be quiet now ;-)  That's a particular sore spot for me anyway.
