I explained that doing so allows for proper formatting of error

Well, I don't think that is the right approach. As many others have
explained, error messages are only a small part of exception handling.
If you do want to have a generic way of getting an error message out of
an exception, what's wrong with toString? Or a new method that formats
the error messages. No need to push up the instance variables to the
base class.
