Supporting this would imply freezing our internal representations of
parse and plan trees (maybe we could move some bits around a little,
but we couldn't make large changes without breaking the XML API).
Like Alex, I don't see any gain that's likely to be worth that price;
especially not when there are so many things I'm unhappy about in both
representations. There are TODO items to revamp both representations
in major ways.
