Yes indeed thats why I was looking for a better solution ;) However I was assuming that if the path was produced by saxon:path() in the link file, and then tested against saxon:path() in the transform, the two would be equal (some kind of normalised path), and so it possibly isnt *that* wrong... I think generating a stylesheet that uses David's key based approach is the way to go here.
