Here's a quick draft that passes check-world, which is enough to give
me no faith whatsoever. Maybe somebody who knows XML better than me
can break it. One thing I'm pretty unsure about is having to cons up
a dummy root node, which is necessary because xmlParseInNodeContext
takes a parent node not a parent doc. Is that correct? In the case
where we don't call xmlParseInNodeContext because the string is empty,
should we still make that node or just leave the document root-less?
