redefine xml schema

[edwong]

Hi all,

I have a xsd file (which I am not allow to change) that contains a complexType called 'AddressType'. Inside this type, there is an element called 'PostalCode' of type xs:string.

Now, I need to do data validation (e.g. ensure it is 5 digits) on 'PostalCode' in another xsd file. Anyone know who to do this? Since I couldn't get the extension/restriction to work.

Thank you

Edmund

<xs:element name="PostalCode">
  <xs:simpleType>
    <xs:restriction base="xs:integer">
      <xs:pattern value="[0-9][0-9][0-9][0-9][0-9]"/>
    </xs:restriction>
  </xs:simpleType>
</xs:element>
