Xwayland is usually spawned by the Wayland compositor which sets the command line options. If a command line option is not supported, Xwayland will fail to start. That somehow makes the Xwayland command line option sort of ABI, the Wayland compositor need to know if a particular option is supported by Xwayland at build time. Also, currently, Xwayland is being installed along with the rest of the common executable programs that users may run, which is sub-optimal because, well, Xwayland is not a common executable program, it's meant to be a proxy between the Wayland compositor and the legacy X11 clients which wouldn't be able to run on Wayland otherwise. Xwayland would be better installed in `libexec` but that directory is (purposedly) not in the user `PATH` and therefore the Wayland compositor may not be able to find Xwayland in that case. To solve both problems (which options are supported by Xwayland and where to look for it), add a `pkg-config` file specifically for Xwayland which gives the full path to Xwayland (`xwayland`) and which options it supports (using `pkg-config` variables). The `pkg-config` file also provides the `Version` so the build scripts can check for a particular version if necessary. Obviously, Wayland compositors are not required to use the `pkg-config` file and can continue to use whatever mechanism they deem preferable.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
