However:

- it's simpler (both to implement and specify) than
oneOrMoreTokens/zeroOrMoreTokens

- it provides some functionality that is legitimate and useful, for example
a list of exactly 4 integers; this is something that XML Schema can do, and
that I expect many people will want, but that we can't support with
oneOrMoreTokens/zeroOneMoreTokens

To me, the increased simplicity is compelling, since simplicity is the main
reason for this whole effort.  I think it's the job of a Schema language to
facilitate good markup design, not to prevent bad markup design.  The only
effective way to prevent bad markup design is to educate schema designers.
