If one looks at the libxml2 like this mirror at [1], it is possible to
see that the flag is only used to lift internal hard limits, for stuff
like XML_MAX_TEXT_LENGTH and XML_MAX_NAME_LENGTH for size control, or
max node depths.
Knowing that we have full control of the memory contexts for the XML
nodes, just enforcing the huge flag does not seem like there's any
downside for us. (Right?)
