If the node returned by a function is a node in the source document, you can use xpaths to navigate away from that, find its parent, look up keys in the same docuemnt etc. If you use copy-of then the function returns a new parentless element node, that has lost its original context, if you apply-template or for-each to move the current context into the node returned you would not be able to get back to the original document (unless you'd saved that original context, say in a global variable) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
