/**
* Specifies a persistent field or property of an entity whose

* <p> The <code>AttributeOverride</code>, <code>AttributeOverrides</code>,
* <code>AssociationOverride</code>, and <code>AssociationOverrides</code>
* annotations may be used to override mappings declared or defaulted
* by the embeddable class.

* @Embedded
* @AttributeOverrides({
* @AttributeOverride(name="startDate", column=@Column("EMP_START")),
* @AttributeOverride(name="endDate", column=@Column("EMP_END"))
* })
* public EmploymentPeriod getEmploymentPeriod() { ... }
