     "Absolutely no doubt"?  Then why is this point being contested by
several GR specialists currently?  Take the 1992 Yu paper as the latest
example.  Can you provide a clear, understandable refutation of his argument?
(See my summary in a simultaneous reply to Matt Austern.)  If so, will you be
publishing a rebuttal?  I'd realy like to get this point cleared up.

     At different points in this discussion I have pointed to evidence for
both of these positions.  The Yu paper clearly is arguing the former
position: there is an ambiguity within GR.  -|Tom|-
