I am really more of a lurker on this list and on the perl-xml list,
but this thread made me wonder if the current SAX support (is it SAX1 or
SAX2),
has the Error Events and the Error Event Handler capabilities?

I am using as a reference (which may not be the same in libxml case):

http://bitsko.slc.ut.us/~ken/perl-xml/sax-2.0-adv.html#Handlers see Error
Events

or in the original SAX2/Java setEventHandler.
