xs:string is unconstrained by default, which (I think) is the
same thing as minLength="0" and maxLength="unbounded".

I don't see any use for a zero length one of these, but I agree this
is a CLR and we should be firm on the introduction of CLRs. In this
case I suggest we let these stand as xs:string's.

Sounds like a good change, I'll update -11 with this change.
