They exist because they existed before the newer classes.  These DOM
and SAX API's conform to the W3C Standards.

Don't use them because you'll probably be more productive and get
better performance using the newer classes.  The standard API's tend
to be un-fun programming and hard to implement.  Further, the
"standard API" doesn't make them as portable as everyone hoped in the
beginning.
