The stub-code is there in XML::SAX::PurePerl, I just never got around to
figuring out exactly what I was supposed to pass to the event. So patches
would be most welcome.

Interesting. dgnorm wasn't available when I wrote the tests originally - is
it freely available now? Also, would XML::Canonical make them representation
independant? Or does dgnorm do more than that? If so, and if dgnorm isn't
freely available, we should port dgnorm to Perl.
