The diagram only represents what is happening from a "user" perspective rather than the "developer" perspective. Much is what is happening with syndication is beneath the application layer (what the users see) and is actually happening at the data layer (what users don't see).

RSS and ATOM represent the “consumer use” of XML, but the real power is perhaps “industrial use”, which translates into data transactions. The School Interoperability Framework (SIF) is one emerging adaptation, but “healthcare” is already well advanced with “transactions processing”.

The diagram cannot be represented as a 2-dimensional model. Almost everything that happens at the “user layer” follows what happens at the “data layer”. To be complete and representative of where things are going requires layers, much like the structure of network architecture.

Without the layering dimension, no such diagram can be complete, prognostic or representative of what is happening with the overall direction of syndication. For example, IPv6 adds two dimensions beyond IPv4, and we still don’t know what this will mean for users.

To explain this a bit further, the development phase of RSS is similar to what we had with black and white television. It is rapidly progressing toward implementation of “color” in a world in which we have HDTV.

If there is a way to represent the diagram as 3-dimensional (or n-dimensional) structure, it would make more sense. It will never be complete as a 2-dimensional model.
