+ * Handles the registration (and unregistration and so on) of managed objects.
+ *
+ * Managed objects are responsible for exposting attributes, operations and notifications. They will expose
+ * these outside the JVM therefore it is important not to use implementation objects directly as managed objects.
+ * Instead, creating inner classes and exposing those is an effective way of exposing internal state in a
+ * controlled way.
+ *
+ * Although we do not explictly use them while targetting Java 5, the enhanced MXBean approach in Java 6 will
+ * be the obvious choice for managed objects.
