Re: node is in a nodelist?

I understand. But with key() as nodelist this is less performant than
David's solution, isn't it?

There are node-sets composed of nodes belonging to different documents
(or even belonging to no document at all).

<xsl:key .../> only indexes the nodes of a single document  (at a
time) and the key() function returns a node-set of nodes, all
belonging to a single document.
