I think that's right (flag XML_PARSE_HUGE shouldn't cause any problems).
My main doubts are related to the replacement of the 
xmlParseBalancedChunkMemory() function (that haven't argument for pass 
XML_PARSE_HUGE flag) with xmlNewNode() + xmlParseInNodeContext() 
functions (create a fake node and pass the XML_PARSE_HUGE flag to 
xmlParseInNodeContext function).

I'm not sure if this replacement is 100% equivalent (although simple 
tests work the same).
