I think there's another very pragmatic rationale as well. If two identical
dateTimes without timezones weren't equal, then the same would logically have
to be true for dates. And then you wouldn't be able to have a simple xs:date
attribute with an enumeration such as

2008-01-31
2008-02-29
2008-03-31
2008-04-30

etc

which would not only introduce a backwards incompatibility, it would also
remove a useful facility with no justification outside the realms of abstract
metaphysics.
