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>
