+//
+// RoutingProxies are client side objects which are used to narrow down
+// into a namespace. They are used to perform ObjectName translation,
+// adding the namespace to the routing ObjectName before sending it over
+// to the source connection, and removing that prefix from results of
+// queries, createMBean, registerMBean, and getObjectInstance.
+// This translation is the opposite to that which is performed by
+// NamespaceInterceptors.
+//
+// There is however a special case where routing proxies are used on the
+// 'server' side to remove a namespace - rather than to add it:
+// This the case of ClientContext.
+// When an ObjectName like "jmx.context//c1=v1,c2=v2//D:k=v" reaches the
+// jmx.context namespace, a routing proxy is used to remove the prefix
+// c1=v1,c2=v2// from the routing objectname.
+//
+// For a RoutingProxy used in a narrowDownToNamespace operation, we have:
+//     targetNs="" // targetNS is the namespace 'to remove'
+//     sourceNS=<namespace-we-narrow-down-to> // namespace 'to add'
+//
+// For a RoutingProxy used in a ClientContext operation, we have:
+//     targetNs=<encoded-context> // context must be removed from object name
+//     sourceNs="" // nothing to add...
+//
+// RoutingProxies can also be used on the client side to implement
+// "withClientContext" operations. In that case, the boolean parameter
+// 'forwards context' is set to true, targetNs is "", and sourceNS may
+// also be "". When forwardsContext is true, the RoutingProxy dynamically
+// creates an ObjectNameRouter for each operation - in order to dynamically add
+// the context attached to the thread to the routing ObjectName. This is
+// performed in the getObjectNameRouter() method.
+//
+// Finally, in order to avoid too many layers of wrapping,
+// RoutingConnectionProxy and RoutingServerProxy can be created through a
+// factory method that can concatenate namespace pathes in order to
+// return a single RoutingProxy - rather than wrapping a RoutingProxy inside
+// another RoutingProxy. See RoutingConnectionProxy.cd and
+// RoutingServerProxy.cd
+//

+// RoutingProxies also differ from HandlerInterceptors in that they transform
+// calls to MBeanServerConnection operations that do not have any parameters
+// into a call to the underlying JMXNamespace MBean.
+// So for instance a call to:
