Embeddable Class
NPersistence Reference Guide
Defines a class whose instances are stored as an intrinsic part of an owning entity and share the identity of the entity. Each of the persistent properties or fields of the embedded object is mapped to the database table for the entity.

Note that the Transient annotation may be used to designate the non-persistent state of an embeddable class.
