/**
* Aggregation property definition.
* <p>
* An aggregation property names one or more managed objects which are
* required by the managed object associated with this property. An
* aggregation property definition takes care to perform referential
* integrity checks: referenced managed objects cannot be deleted. Nor
* can an aggregation reference non-existent managed objects.
* Referential integrity checks are <b>not</b> performed during value
* validation. Instead they are performed when changes to the managed
* object are committed.
* <p>
* An aggregation property definition can optionally identify two
* properties:
* <ul>
* <li>an <code>enabled</code> property in the aggregated managed
* object - the property must be a {@link BooleanPropertyDefinition}
* and indicate whether the aggregated managed object is enabled or
* not. If specified, the administration framework will prevent the
* aggregated managed object from being disabled while it is
* referenced
* <li>an <code>enabled</code> property in this property's managed
* object - the property must be a {@link BooleanPropertyDefinition}
* and indicate whether this property's managed object is enabled or
* not. If specified, and as long as there is an equivalent
* <code>enabled</code> property defined for the aggregated managed
* object, the <code>enabled</code> property in the aggregated
* managed object will only be checked when this property is true.
* </ul>
* In other words, these properties can be used to make sure that
* referenced managed objects are not disabled while they are
* referenced.
*
* @param <C>
* The type of client managed object configuration that this
* aggregation property definition refers to.
* @param <S>
* The type of server managed object configuration that this
* aggregation property definition refers to.
