Forgive my tardy response to your reply @kerry_s.
Forgive my lack of detail knowledge regarding X11, as I understand it, it is a communications protocol that is used between one device and the next.
Not wholely. It's an API for GUI applications. The applications use the API to communicate with the X server which handles the lower level stuff so the applications don't have to. It also uses the API in the other direction to get keyboard, mouse and other event data. X applications don't care, and may not know, whether the application and the X server are running on the same box or not.
Further, it appears that XRDP is not an X server. It uses (or starts) an Xvnc server or X server and sends the generated desktop to the remote client using MS' RDP protocol.
