Notes on the Saxon implementation
This function is retained in Saxon for backwards compatibility as it is widely used in
XSLT 1.0 stylesheets, however it is simply a no-op, because the restrictions on use of
node-sets that made it necessary have disappeared. The input can be any sequence, and it
is returned unchanged. This differs from some implementations of the
node-set() function which, for example, did the equivalent of
parse-xml() if supplied with a string as input.
