I agree with Amy. Yes, the DOM interfaces have a fly() method
on the base Bird interface when most of the birds in question
are flightless waterfoul but I see this as a good thing. In
Java you avoid the runtime check for ClassCastException by
being able to do "node.getAttributes()" instead of
"((Element)node).getAttributes()".
