The following example shows a simple type definition of a string type
based on a restriction using the xs:length element. The defined
type only accepts strings that are 8 characters long:
<xs:simpleType name="code">
<xs:restriction base="xs:string">
<xs:length value="8"/>
</xs:restriction>
</xs:simpleType>
