jaxb2 & xjc - generate fields with inherited type - jaxb

Question

I'm having some trouble with an xsd that was supplied to us. I'm not really sure how to describe my issue without example so I created a test xsd that has the same issue.
Here's the xsd:
<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="shiporder" type="shipordertype"/> <!-- note: name is equal to name of a complex type further down -->
<xs:complexType name="shiptotype">
<xs:sequence>
<xs:element name="name" type="stringtype"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="myshiptotype">
<xs:complexContent>
<xs:restriction base="shiptotype">
<xs:sequence>
<xs:element name="name" type="stringtype">
<xs:annotation>
<xs:documentation source="Yellow Field"/>
</xs:annotation>
</xs:element>
</xs:sequence>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
<xs:complexType name="shiporder">
<xs:sequence>
<xs:element name="orderperson" type="stringtype"/>
<xs:element name="shipto" type="shiptotype"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="shipordertype">
<xs:complexContent>
<xs:restriction base="shiporder">
<xs:sequence>
<xs:element name="orderperson" type="stringtype"/>
<xs:element name="shipto" type="myshiptotype">
<xs:annotation>
<xs:documentation source="Yellow Field"/>
</xs:annotation>
</xs:element>
</xs:sequence>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
<xs:simpleType name="stringtype">
<xs:restriction base="xs:string"/>
</xs:simpleType>
</xs:schema>
I've got this external binding file:
<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
version="2.1">
<jaxb:bindings schemaLocation="test.xsd" node="/xs:schema">
<jaxb:bindings node="//xs:complexType[#name='shiporder']">
<jaxb:class name="InnerShipOrder" />
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
Now when I generate java classes I get the following classes:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "shipordertype")
#XmlRootElement(name = "shiporder")
public class Shiporder
extends InnerShipOrder
implements Serializable
{
private final static long serialVersionUID = -1L;
}
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "shiporder", propOrder = {
"orderperson",
"shipto"
})
#XmlSeeAlso({
Shiporder.class
})
public class InnerShipOrder
implements Serializable
{
private final static long serialVersionUID = -1L;
#XmlElement(required = true)
protected String orderperson;
#XmlElement(required = true)
protected Shiptotype shipto;
// some getter and setter functions
Now, in the xsd the shipordertype has a 'shipto' field of the type 'myshiptotype'. However in the generated classes, shipordertype extends shiporder which has a 'shipto' field of the type 'shiptotype'.
Is it possible to make it so that the generated ShipOrder class has a 'shipto' field of the 'myshiptotype'?
