It's either the difference between strongly and weakly typed languages
or an as-yet-unrecognized difference in design pattern, but the
marriage of SAX and DOM in Perl, using Perl style APIs, results in
fewer classes/interfaces than in just SAX alone in Java.  The same
patterns work very well in Python and Tcl, and even C, but are having
troubles being ported back to Java/C++.

As we move more code into this framework, we've found the resulting
code to be quite a bit simpler overall.
