see the identity function example that i gave. 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)
