Yes. It was (by luck) one of those errors that type checking does catch. I
fully agree that there are many errors that type checking does not catch.
But my experience with XSLT 2.0 is that type checking catches a very useful
proportion of errors, sufficient to make a lazy programmer (me) get into the
habit of declaring types on all my variables and parameters.
