RE: Node-List in Variables

Firstly, you don't need to write this. It's been done before: see
http://www.exslt.org/str/functions/tokenize/str.tokenize.template.xsl

(use "view source" in your browser if nothing shows).

But the only thing wrong with your code, as far as I can see, is that
the variable $tlist is not a sequence of elements, but a document node
that is the owner of that sequence of elements.
