> It would be nice if there was a way pages could define an event handler that
> would be notified in the event of an exception while processing the page; it
> should be passed the exception and some indicator (an enum) of where the
> exception occurred. This would allow a way for individual pages to handle
> certain exceptions in a specific way.
> A particular use case for this would be handling the case where parameters
> can not be coerced when invoking an activate event handler method, but
> there's quite likely many others.
