As those points depict, I think the idea of the layer cake is also to have a simple (but maybe not complete or even completely correct) diagram to tell people, what you are doing. E.g. where about your technology/methodology/software/standard/… is located and what it cares about. I think specification of all the stuff is done in other places. Further: sorry I didn't want to unleash the whole debate about the XML Layer again. But since I can't keep my comment behind: I think RDF still inherited concepts from XML, e.g. namespace (https://www.w3.org/TR/2009/REC-xml-names-20091208/). So the layer should not stand for all serialization formats, but for some fundamental concepts. Finally, I assume the Layer Cake (https://www.w3.org/2007/03/layerCake.svg) stands for itself and it is up to us, to add further interpretation, as we like … (while there is no enclosing document).
