How about this:
public class Person {
private AddressGroup fAddressGroup;
...
/** Convenience method: create AddressGroup and set addresses indirectly */
public void setAddresses(List addresses) {
fAddressGroup = new AddressGroup(addresses);
}
/** Convenience method: retrieve addresses from my AddressGroup */
public List getAddresses() {
return fAddressGroup.getAddresses();
}
}
Map Person to the PERSON table and Address to the ADDRESS table; nothing weird
required in repository.xml.

It is purely a domain class.
