-	- TCFMessage::TErrorRecoveryRequest	=> TNodeMessage::TErrorRecoveryRequest
-
-- Iterators use TClientType::TCFClientType:

-	- RNodeInterface::EData			=> TCFClientType::EData
-	- RNodeInterface::ESecondary		=> TCFClientType::ESecondary

-
-	- CFNODE_SET_CLIENT_TYPENFLAGS(RNodeInterface::EVAL1, RNodeInterface::EVAL2)
-		=>
-	  TClientType(TCFClientType::EVAL1, TCFClientType::EVAL2)
-
-- Messages no longer need to be constructed with sender and activity:
-	- TCFMessage::MSG(const ESock::TCommsId& aSenderId, TUint aActivityId, ...) => TCFMessage::MSG(...)
-	- ESock::TCFSignatureBase(aMessageId, aSenderId, aActivityId)		    => Messages::TSignatureBase(aMessageId)
-
-- PostToClients<T>() arguments have changed:
-	- PostToClients<T>(MSG&, RNodeInterface::EA)  =>  PostToClients<T>(const TNodeCtxId &, MSG&, TClientType(TCFClientType::EA));
-
-- PostToSender() applies to context rather than message:
-	- MSG1.PostToSender(MSG2) => iContext.PostToSender(MSG2)
-
-- PostTo() can be simplified to use PostToSender() in some cases:
-	- MSG(iContext.Node()(),iContext.iCFMessageSig.ActivityId(),...).PostTo(iContext.iCFMessageSig.iSender);
-			=>
-	  iContext.PostToSender(MSG(...));
-
-- MSG::PostTo() replaced with OpenPostMessageClose():
-
-	- MSG.PostTo(iNode());	// self
-			=>
-	  TNodeCtxId us(ActivityId(),iNode.Id());
-	  RClientInterface::OpenPostMessageClose(us, us, MSG());
-
-	- MSG.PostTo(iContext.Node()());
-			=>
-	  RClientInterface::OpenPostMessageClose(TNodeCtxId(iContext.ActivityId(), iContext.NodeId()),
-		  iContext.NodeId(), MSG());
-
-	- MSG.PostTo(iContext.Node()());
-			=>
-	  RClientInterface::OpenPostMessageClose(iContext.NodeId(), iContext.NodeId(), MSG());
-
-	- MSG(const TCommsId* src, ...).PostTo(const TCommsId& dest);
-		=>
-	  RClientInterface::OpenPostMessageClose(const TRuntimeCtxId& src, const TRuntimeCtxId& dest, MSG());
-
-	- TCommsId dest = ServiceProviderL();
-	  TCommsId self = NodeId();
-	  MSG(self, ACTIVITYID).PostTo(dest);
-		=>
-	  TNodeCtxId us(ACTIVITYID, NodeId());
-	  RClientInterface::OpenPostMessageClose(us, ServiceProviderL(), MSG());
-
-	- MSG.PostTo(RNodeInterface&);
-			=>
-	  RClientInterface::OpenPostMessageClose(Id(), RNodeInterface&, MSG);
-
-	- MSG.PostTo(self) => iNode.SelfInterface().PostMessage(self, MSG); 	// ??
-
-- RClientInterface::PostMessage(MSG);
-		=>
-  activity.PostRequestTo(RClientInterface&, MSG());
-
-- where a message used to be passed before, now message and runtime/node context are needed:
-
-	- void f(TMyMessage& aPolicyParam)  =>  void f(const Messages::TRuntimeCtxId& aSender, TMyMessage& aPolicyParam);
-
-	- INMSG.iSender = iContext.Node()();
-	  INMSG.SetActivity(iContext.iNodeActivity->ActivityId());
-	  iContext.Node().PostToClients<TPolicy>(INMSG, RNodeInterface::EData);
-			=>
-	  iContext.Node().PostToClients<TPolicy>(TNodeCtxId(iContext.ActivityId(), iContext.NodeId()), INMSG, TClientType(TCFClientType::EData));
-
-	- RNodeInterface::PostMessage(MSG) => RNodeInterface::PostMessage(TNodeCtxId(activityId, nodeId), MSG);
-
-	- TNodeContext<TNODE>(TNODE&, TSignatureBase& aMessage, const TRunTimeCtxId& aSender, const TNodeId& aRecipient, CNodeActivityBase* aNodeActivity = NULL);
-
-- on nodes, operator()() is replaced with Id():
-	- (*this)() => Id()
-	- NODE()    => NODE.Id()
-
-- iContext.iCFMessageSig.iPeer->PostMessage(MSG);
-		=>
-  iContext.PostToSender(MSG);
-
-- there are changes to the way activities can be retrieved:
-	- iContext.Node().FindAddressedActivity(iContext.iCFMessageSig)
-		=>
-	- TUint sendersActivityId = address_cast<TNodeCtxId>(iContext.iSender).NodeCtx();
-	  iContext.Node().FindActivityById(sendersActivityId)
-
-- TCFMessageSig<xxx> replaced with TMessageSig<xxx>
-	- ESock::TCFMessageSigNumber<EMSGID, EREALM> TMyMessage  =>  Messages::TMessageSigNumber<EMSGID, EREALM> TMyMessage
-
-- Retrieval of sender from a message is replaced with retrieval from context:
-	- MSG.iSender					=> iContext.iSender
-	- iContext.iCFMessageSig.iSender.NodePtr()	=> address_cast<TNodeId>(iContext.iSender).Ptr()
-
-- TErrContext:iActivityId => TErrContext:iActivitySigId
-
-- TCommsId is replaced with Messages::TNodeId:
-
-	- TCommsId::NullCommsId()	=> TNodeId::NullId()
-	- TCommsId::operator()()	=> TNodeId::Id();
-
-	- TRuntimeCtxId sometimes used in place of TCommsId (?)
-
-- ReceivedL() method signatures have changed.  May need to add User::LeaveIfError(...) to some ReceivedL() routines.
-
-- Changes to iContext data member names and methods:
-	- iContext.iCFMessageSig		=> iContext.iMessage
-	- iContext.iCFMessageSig.iCommsId	=> iContext.iMessage.iNodeId;
-	- iContext.iCFMessageSig.iPeer		=> iContext.iPeer
-	- iContext.iCFMessageSig.iSender	=> iContext.iSender
-	- iContext.Node()()			=> iContext.NodeId()
-	- iContext.iNode()			=> iContext.NodeId()
-
-- Changes to the way MPlatSecApiExt is retrieved:
-	- MPlatsecApiExt* platsec = iContext.iCFMessageSig.FetchPlatsecApiInterfaceL()
-		=>
-	  MPlatsecApiExt* platsec = reinterpret_cast<MPlatsecApiExt*>(address_cast<TNodeId>(iContext.iSender).Node().FetchNodeInterfaceL(EPlatsecApiExt));
-
-- Header files have moved location:
-	- ss_factnotify.h			=> elements/factorynotify.h
-	- comms-infras/sm_core.h		=> elements/sm_core.h
-	- comms-infras/sm_statetriple.h		=> elements/sm_statetriple.h
-	- comms-infras/ss_nodestates.h		=> elements/mm_states.h
-	- comms-infras/ss_nodeactivities.h	=> elements/mm_activities.h
-	- comms-infras/interfacetable.h		=> elements/interfacetable.h
-	- comms-infras/cftransport.h		=> elements/cftransport.h
-	- comms-infras/ss_nodeactivities.h &	=> comms-infras/ss_common.h (?)
-	  comms-infras/ss_nodemessages.h
