Hi Max,

it is not necessary to put this into the Kernel_traits, since only Nef
polyhedra use extended kernels. The class Nef_polyhedron_3 has static
functions

bool is_standard_kernel()
bool is_extended_kernel()

Also the type 

CGAL::Is_extended_kernel<Kernel>

evaluates to Tag_true or Tag_false depending on the given Kernel. If
Is_extended_kernel is not known, then include CGAL/Is_extended_kernel.h.
