need some explanation about strange JAXB generated code

[nicolas de loof]

Hello,
My WSDL sxhema defines a complextype :

   <xs:complexType name="SaisieActeMessage">
     <xs:sequence>
         <xs:element name="adressefacturation" type="tns:Adresse"/>
         <xs:element name="adresselivraison" type="tns:Adresse"/>
         <xs:element name="contact" type="tns:MoyenDeContact"/>
[~10  more elements] ...

I expected the generated Java class to define attributes
"adressefacturation", "adresselivraison", "contact" ..., as it does for many
other types in my WSDL, but I get :

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "SaisieActeMessage", propOrder = {
    "content"
})
public class SaisieActeMessage {

    @XmlElementRefs({
        @XmlElementRef(name = "adresselivraison", namespace = "http://foo";,
type = JAXBElement.class),
        @XmlElementRef(name = "adresseFacturation", namespace = "http://w foo",
type = JAXBElement.class),
        @XmlElementRef(name = "contact", namespace = "http://foo";, type =
JAXBElement.class),
.....    })
    protected List<JAXBElement<?>> content;


Is this REALLY what is expected ? Is there no way to have something more
developer-compliant ?
