Not now! Everyone agrees that we need datatypes. I expect some cheerful
& constructive bloodletting in the SIG & WG as to which set of datatypes
we need. Anybody who invests effort in that set at this time is spinning
wheels.
On the other hand, bearing what you say in mind, I think there may be
a sane case to be made for decoupling the task of identifying the set
of datatypes from that of defining the rest of the schema mechanics;
however we end up specifying the datatypes, the heavy typechecking
coding will be about the same, and it might be nice to give that a
head-start.
>I note that max and min have changed from being content to attributes.
No! Read the early part of the spec. Per RDF, these things are
*properties*, which can be given either as elements or attributes.
