In an attempt to be less argumentative I replied earlier today
essentially retracting my earlier claim, but you lead me astray:-)
I was right the first time:

There is not a fixed extension URI, you just make them up as you go along: 

   A call to a function ns:foo where ns is bound to a namespace of the
   http://www.jclark.com/xt/java/className is treated as a call of the
   static method foo of
   the class with fully-qualified name className.

In otherwords _anyone_ gets to chose the className from some class on
their java classpath and refer to that class via a namespace URI of the
above form. oracle xalan and saxon have similar namespace usage.
