Are Restrictions ignored by wsdl2java?

[GEORGE MCKINNEY]

We used the wsdl2java to generate the types etc needed for a client that will 
talk SOAP.

Things are working (with a few tweaks ), but I notice that although the schema 
includes bits like:

    <xs:simpleType name="ClientNumber">
        <xs:restriction base="xs:string">
            <xs:pattern value="[A-Z0-9]{1,9}" />
        </xs:restriction>
    </xs:simpleType>

defining the type of an Element, the generated Java doesn't (as far as I can 
tell ) enforce that at all, although it does generate enumeration type classes 
for xml like: 

    <xs:simpleType name="ProductType">
        <xs:restriction base="xs:string">
            <xs:enumeration value="AAA" />
            <xs:enumeration value="BBB" />
            <xs:enumeration value="CCC" />
        </xs:restriction>
    </xs:simpleType>

Is this the way it is intended to work, or am I missing something?

Thanks,
