Previously, if you, for example, set
services.xserver.displayManager.sddm.enable, but forgot to set
services.xserver.enable, you would get an error message that looked like
this:
error: attribute 'display-manager' missing
Which was not particularly helpful.
Using assertions, we can make this message much better.
