E2-35 [1] makes the following declarations valid:

<xs:simpleType name="st1">
  <xs:restriction base="xs:string">
    <xs:length value="5"/>
  </xs:restriction>
</xs:simpleType>

<xs:simpleType name="st2">
  <xs:restriction base="st1">
    <xs:minlength value="2"/>
  </xs:restriction>
</xs:simpleType>

But the second derivation step doesn't seem to mean anything. This is
analogous to having minInclusive=10 in the base and minExclusive=0 in the
derived, which is not allowed by the spec.

It seems to be a good change to allow "length" after "min/maxLength", but
not the other way around.
