CREATING NEW EXCEPTION CLASSES
All you need to do to create a new exception class is:
@XML::SAX::Exception::MyException::ISA = ('XML::SAX::Exception')

may also inherit from that instead of from the base class.
This is as simple as exemplified in the SYNOPSIS.
In fact, there's
nothing more to know. All you have to do is:
throw XML::SAX::Exception::MyException( Message => 'Something went wrong' );
and voila, you've thrown an exception which can be caught in an eval block.
