I regret to say that (unless I've missed something) the above is
completely legal in XSLT 2.0.
I fought hard to disallow this, because I know how many beginners
misunderstand variables, and lost. There are too many people steeped in
functional programming who can't see why it's a problem.
I'm sure the debate is one that will be revived during the public
comments cycle - as I said, it's a bicycle shed issue.
