OK, I'll leave that part out.

I need two macros -- one which has the same definition as the
current IsXactIsoLevelSerializable, to be used everywhere the old
macro name currently is used, which conveys that it is an isolation
level which is based on a transaction snapshot rather than statement
snapshots (i.e., REPEATABLE READ or SERIALIZABLE) and a new macro
(which I was planning to call IsXactIsoLevelFullySerializable) which
conveys that it is the SERIALIZABLE isolation level. Do you feel
that IsXactIsoLevelSnapshot works with
IsXactIsoLevelFullySerializable to convey the right semantics? If
not, what would you suggest?
I'm not attached to any particular names; what matters is that when
people see them, they get the right meanings from them. I have some
concern that IsXactIsoLevelSnapshot might suggest that it excludes
the fully serializable transaction isolation level.
