Let me get to the heart of it, is the layer a property of a system or
of a set of systems? Can I have a layer in the traditional sense in
a single system?

Not quite sure what you mean here. Are you referring to Dykstra's
concept that the functions included in a given layer do not need to
be replicated at higher layers?
