RE: [xsl] Parameters into variables

It's always useful, rather than saying "it doesn't work", to say exactly how
it fails. Error message? Wrong results?

I can't see anything wrong with your code, it looks perfectly legal to me -
but I'm trying to debug it without the benefit of seeing its output.
