/**
* Specifies a persistent field or property of an entity whose
* value is an instance of an embeddable class. The embeddable
* class must be annotated as {@link Embeddable}.
*
* The AttributeOverride, AttributeOverrides,
* AssociationOverride, and AssociationOverrides
* annotations may be used to override mappings declared or defaulted
* by the embeddable class.
*
*
* Example:
*
* @Embedded
* @AttributeOverrides({
* @AttributeOverride(name="startDate", column=@Column("EMP_START")),
* @AttributeOverride(name="endDate", column=@Column("EMP_END"))
* })
* public EmploymentPeriod getEmploymentPeriod() { ... }
