Two reasons:

1. Using java.lang.Object will make ModSAX Java-dependent.
2. Using ModHandler interface adds some compile-time type-check.

Only penalty is increasing the number of interfaces a class implements which
does affect the performance during runtime.  Very little penalty in most

Most Java VM implementations search the interface list back to front so that
most often used interface (i.e. org.w3c.dom.Node) should be the last
interface in the 'implements' list.
