Jim already mentioned a customised view on the exception.

Another option that is not as architecturally clean, but might work 
better for you, is to catch the exception, but doom the transaction.

I wonder if it's a good idea to support having an application say "I 
want to doom this transaction", and have the publication object just 
abort that transaction without returning an error page.
