How can I define a Custom Value Type that has a Many-to-One association?

----
Sample
----
In this case I want to define a custom value type to persist the property
address of the customer.
--
Customer
-
String name
Address address
--

--
Address
-
String street
City city
--

--
City
-
String name
--

have you read 'Chapter 7. Component Mapping' of the Hib' docs?

Thank you and forgives my distraction!
