JAXB / XJC parent-child-parent navigation

Question

i would like to have bidirectional navigation methods in classes between child object and parent object. IDREF is not enough in my case because I don't want to specify le id of parent. to be clear, from an xsd like that:

<complexType name="A">
    <xs:sequence>
        <element name="b" type="B" minOccurs="0" maxOccurs="unbounded"></element>
    </xs:sequence>
    <attribute name="id" type="ID"></attribute>
</complexType>
<complexType name="B">
    <attribute name="id" type="ID"></attribute>
</complexType>

i would like classes looks like this:

class A {
    ...
    public List<B> getB() { ...}
    ...
   }
class B {
    ...
    public A getA() {
    ...
}

and my xml must looks like this:

<a id="a1">
    <b id="b1"/>
    <b id="b2"/>
    ...
</a>

After unmarshal, I would like to be able to navigate A to Bs AND from B to A (via b.getA()) !! It a very basic feature, but I don't find a simple way to achieve that ...

Any idea ??

Thanks in advance

You can create a method void afterUnmarshal(Unmarshaller, Object parent) that gets called... well, after unmarshalling and set up your object tree as you need it.
