Wondering if there is an example somewhere of how to define an extension function prior to compiling and invoking the XQuery.
The key requirement of this function is that when it is executed it must be able to transparently access the context node of the XQuery expression being executed (i.e. context node doesn't have to be explicitly passed by the user).
Hence, I don't think I can just use the standard Java extensibility provided by Saxon, but suspect I have to create something similar to the VendorFunctionLibrary provided by Saxon.
Any/all help would be greatly appreciated,
