Generated WSDL with schema validation

[Ole Hornischer]

Hi!
Is it possible to add schema restrictions to parameters via JAX-WS annotations?

Example:
I have a method

@WebMethod
ReturnContainer<List<Street>> getStreets(@WebParam(name = "streetname")String streetname);

The parameter streetname should always be longer then 3 characters, to avoid gigantic result lists. I would like this to be a restriction in the schema like
<xs:element name="streename"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="3"/> </xs:restriction> </xs:simpleType> </xs:element>
How can I make sure that the generated WSDL file includes such a restriction on the parameter?

Cheers
Ole
