[SyncEvolution] Location of Synthesis in Syncevolution architecture diagram ?

Where would the synthesis library be in the diagram on the web site see: http://syncevolution.org/development/direct-synchronization-aka-syncml-se... I think it would be nice to add it to the diagram. I believe in the HTTP scenario, it would be a small rectangle inside the syncevo-dbus-server. It would also might be helpful to label the http daemon edge to dbus edge as SyncML
