<!-- 

  This mapping demonstrates shared PK one-to-one associations using
  lazy="proxy" and lazy="no-proxy".

  Implementation note: This test does not include any other
  lazy properties, and allows testing special case code in
  AbstractEntityPersister.initializeLazyPropertiesFromDatastore()
  (lazy select string will be null) and OneToOne.nullSafeGet()
  (ResultSet arg is ignored and the owner's ID is returned).
