/**
 * 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>
