Can jaxb2-basics be configured to specify an interface for a type variable of a generic object?

I am using jax-ws's wsimport to generate java classes from WSDLs. I am using the jaxb2-basics plugin to create toString, equals, hashCode, copy, and merge methods.

I would like for the generated classes to implement interfaces to insulate our code from the implementation if we ever need to change it.

I would like to use jaxb2's ability to generate classes that implement a specified interface with limited success. It is not enough for the classes to implement an interface. I want generated classes that are composed of other generated classes to use interfaces instead of implementations when it refers to those objects.

I am using an external bindings file to define the interface that a class should implement:

<jaxws:bindings

xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
            xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
            xmlns:s="http://www.w3.org/2001/XMLSchema"
           xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
           wsdlLocation="ExampleService.wsdl"
           xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
           jaxb:extensionBindingPrefixes="inheritance">

<!-- Person -->
<jaxws:bindings node="wsdl:definitions/wsdl:types/s:schema[@targetNamespace='http://example.com/ws']">
    <jaxb:bindings node="//s:complexType[@name='Person']">
            <inheritance:implements>com.example.IPerson</inheritance:implements>
    </jaxb:bindings>
</jaxws:bindings>

<!-- Bus -->
<jaxws:bindings node="wsdl:definitions/wsdl:types/s:schema[@targetNamespace='http://example.com/ws']">
    <jaxb:bindings node="//s:complexType[@name='Bus']">
            <inheritance:implements>com.example.IBus</inheritance:implements>
            <jaxb:bindings node="//s:element[@name='Driver']">
                <jaxb:class ref="com.example.IPerson"/>
            </jaxb:bindings>
            <!-- How to do this? This doesn't work.
            <jaxb:bindings node="//s:element[@name='Passengers']">
                <jaxb:class ref="java.util.List&lt;com.example.IPerson&gt;"/>
            </jaxb:bindings>
             -->

    </jaxb:bindings>
</jaxws:bindings>

For instance, if I have a class called Bus and it has a class called Person in it, I want Bus to implement IBus, Person to implement IPerson, and Bus to have a member variable of type IPerson, not Person.

public Class Bus implements IBus {

    protected IPerson driver;
    ...
}

What I have in the bindings file is working.

But, if Bus has a List of Person objects, I cannot get wsimport to generate a class for Bus that defines a List of IPerson objects.

public Class Bus implements IBus {

    protected IPerson driver;
    protected List<IPerson> passengers;
    ...
}

Here is the example wsdl I used (silly and stupid example, but it gets the point across):

Does anyone know if it is possible to get jaxb2-basics to generate a generic object whose type variable is specified in a jaxb bindings file?

No, it is not possible at the moment.

UPDATE

This has now been implemented in 0.6.4.
