XWayland security, equals to X11 or Wayland?

Hi there, I try to get into Wayland as it promises to separate applications from each other. With X11, every application can get all event inputs and window contents of every other running application. AFAIK this issue is solved with Wayland. Now, we will need to have XWayland running for a long time until everything is recompiled with Wayland support. My question is, on which side does XWayland operate? From the highlevel documentation at http://wayland.freedesktop.org/xserver.html I conclude, that the X11 support is done via having a single Wayland client which then multiplexes the stuff internally to all X11 clients. So my guess is, that all X11 applications that work via XWayland have access to eachother but not other native Wayland clients. Or are the X11 clients already separated ike Wayland clients, so that this security aspect is already solved for those? Please correct me if I have any wrong conclusions or knowledge.
