/**
* <p>
* This interface is implemented by a JavaBean that does
* not directly have a BeanContext(Child) associated with
* it (via implementing that interface or a subinterface thereof),
* but has a public BeanContext(Child) delegated from it.
* For example, a subclass of java.awt.Container may have a BeanContext
* associated with it that all Component children of that Container shall
* be contained within.
* </p>
* <p>
* An Object may not implement this interface and the
* BeanContextChild interface
* (or any subinterfaces thereof) they are mutually exclusive.
* </p>
* <p>
* Callers of this interface shall examine the return type in order to
* obtain a particular subinterface of BeanContextChild as follows:
* <code>
* BeanContextChild bcc = o.getBeanContextProxy();
*
* if (bcc instanceof BeanContext) {
* // ...
* }
* </code>
* or
* <code>
* BeanContextChild bcc = o.getBeanContextProxy();
* BeanContext bc = null;
*
* try {
* bc = (BeanContext)bcc;
* } catch (ClassCastException cce) {
* // cast failed, bcc is not an instanceof BeanContext
* }
* </code>
* </p>
* <p>
* The return value is a constant for the lifetime of the implementing
* instance
