xpath_table is severely broken by design IMNSHO. We need a new design, 
but I'm reluctant to work on that until someone does LATERAL, because a 
replacement would be much nicer to design with it than without it.

But I don't believe replacing the underlying XML/XPath implementation 
would help us fix it at all.
