Steffi, I look forward to someone shedding some light on this too.

Right now we are using the Abort() call and requiring the
user to use the browser "back" button. It's very ... 1995.

*I* am not aware of any clean way to do what would be desired
by anyone wanting to do something like this:

    Evaluate custom logic at Modify.html submission (and
    Update.html!), take no action and redisplay the form
    with error message if the logic requirements are not met.
