Yeah. It's annoying as heck, because they deprecated that without
providing an adequate replacement. The replacement is claimed to
be "Use the modern options API with XML_PARSE_NOBLANKS", but there
is no direct equivalent to xmlParseBalancedChunkMemory that takes
an options argument.

So to get rid of this, we're looking at a probably-nontrivial
rewrite of xml_parse(), with possibly some user-visible behavioral
changes, and who-knows-what effects for compatibility across
different libxml2 versions.

If you feel like researching that, have at it.
