Speaking for myself, I think the intention you describe is indeed 
compatible with XSD 1.1's definition of the datatypes in question.

It should be pointed out, however, that the timeline in question is
not necessarily continous -- or at least, that its mapping onto UTC
is not continuous.  Since XSD 1.1 does not provide for, support, use,
or countenance leap seconds, the values of our dateTime datatype map
discontinuously onto the UTC timeline.  If this matters in your use of
the type, be careful.  (Of course, many systems handle leap seconds
in roughly the same way XSD does; by scrupulously noting their existence,
but ignoring them for almost all practical purposes.)
