I must have drunk too much at the reception 'cause I'm going to try to
stick up for McInnes B T (Dr).  He is not contradictory if he assumes
that spacetime is a semi-Riemannian manifold, hence a set of point, and
if he assumes that each point is, or designates, an event.  The latter
is pretty standard GR rhetoric, but don't ask me what an "event" is or
I'll just say "a point in spacetime."  :-)

By the way, I love the subject line except for that extra "Z" which I am
assiduously deleting.
