/**
* Interfaces and classes for general purpose registries.
* A registry is like a <code>Map</code> but has some additional features:
* <ul>
* <li>It provides a descriptor framework for registry elements that
* are to be instantiated lazily
* <li>It provides a notification framework that enables clients to
* react on events (including the resolution of a lazy descriptor)
* </ul>
