Internal Program Version: XML::SAX::Base  1.09.5.42.0

This module has a very simple task - to be a base class for PerlSAX drivers
and filters. It's default behaviour is to pass the input directly to the
output unchanged. It can be useful to use this module as a base class so
you don't have to, for example, implement the characters() callback.
