xslt diff

Has anyone come up with a way to generate an XSLT that when applied to one
document would produce another, a la diff? PaulT posted something on the
subject a couple of months ago, but his site says the code is frozen.

Obviously, a trivial solution is to have a literal result that's a copy of
the second document :=)
