Actually, Saxon currently implements all the Saxon extension functions as if
they were user-written functions, the only special treatment is that the
Saxon namespace is a synonym for the full namespace for the relevant class.
This prevents me doing some optimizations (as in the case of saxon:if()),
but ensures that anything I need to do to support my own extension functions
is also available for user-written functions.
