   7Seven base quantities in the SI system. In RS framing, five are
   8kinematic/dynamic (= configDim D = 5):
   9  length, mass, time, electric current, temperature.
  10
  11Plus two auxiliary (amount-of-substance, luminous-intensity) which
  12are derivable from the five via mole and photon counts.
