  Another problem is that the xml:base which needs to be added is dependant
on the location of the test-suite at runtime unless one proceed to do
some convoluted URI relativization of the xml:base values.

  Well in general, I think the goal is more to exercize the spec being
tested and have unanbiguous results w.r.t. that given specification,
chasing a more general goal which is to provide a regression tests
valid for all implementations is far more costly, I'm not sure the
Working Group really have the cycles to reach that goal, nor that it's
really what we want to guarantee.
