Specifically, it's the 'rng-state' property on the "</p>" that ends a
paragraph.  It's a massive recursive data structure, and printing it
takes a lot of memory.  Maybe nXML could arrange for these properties
to be removed when copying to the kill-ring, but would it get in the
way if you want to paste into an XML buffer?
