As I mentioned it my other message, I think changing the validator
to not run XML wf-ness checks on text/html pages by default might
help greatly with this problem.

But I also want to ask: When XML::LibXML is used for wf-ness
checking, is it currently reading the contents of each page into a
DOM? If so, is there a way to have it run in SAX/streaming mode
instead? And if so, can we having to just fail at the first
well-formedness error?
