I will address some of your comments now and others when I have more time.

This one has been added to the list of places where the spec is ambiguous
and needs to be clarified, thanx.

Since the value spaces of float, double and integer are disjoint, it follows
("is a consequence..") that the literal "3" these types maps to different
values that are not equatable.

As Ashok has mentioned, the working group is considering changing that
property from antisymmetry to asymmetry (a < b implies not (b < a)), which
in the present context amounts to the same thing but is less likely to
engender comments such as yours (the current formulation is more natural for
relations such as <=).

I think you might be right, but I'm not sure.  I'll bring this one up with
the WG.  In the end, however, this might not be the kind of thing that we
can correct before going to REC.
