As I said in a reply to your previous message, you do not need to use a
namespace prefix to call functions in the standard function library.
However, if you do use one, you must get the namespace declaration right.
The correct URI is:

http://www.w3.org/2003/11/xpath-functions

The error message is a little obscure, because Saxon's "last resort" for
loading functions with an unknown URI is to try to use the URI to local a
Java class containing extension functions.
