/**
* Annotation used to indicate that associated property is part of
* two-way linkage between fields; and that its role is "child" (or "back") link.
* Value type of the property must be a bean: it can not be a Collection, Map,
* Array or enumeration.
* Linkage is handled such that the property
* annotated with this annotation is not serialized; and during deserialization,
* its value is set to instance that has the "managed" (forward) link.
*<p>
* All references have logical name to allow handling multiple linkages; typical case
* would be that where nodes have both parent/child and sibling linkages. If so,
* pairs of references should be named differently.
* It is an error for a class to have multiple back references with same name,
* even if types pointed are different.
*<p>
* Note: only methods and fields can be annotated with this annotation: constructor
* arguments should NOT be annotated, as they can not be either managed or back
* references.
