Obviously, V2 does not have namespace-aware XML scanner handy. The best 
approach would be, ehm... build bjam with python support, with:

  ./build --with-python=/usr

on Linux and with

   build.bat --with-python=whatever

on Windows, and run the attached files with:

  bjam -fpytest.jam

The same importing logic can be used in regular Jamfiles.
