When you say "auto-referencing" do you mean the same as "self-reference" (the term I used originally)? I talked about self-referencing in connection with my proposal to use topic maps to represent PSI sets. I was faced with two questions: - how to specify the published subject identifier, and - how to differentiate between topics intended to be used as PSIs and other topics The solution (to which, by the way, I am by no means wedded) was to specify the subject identity of a PSI topic using a subject indicator reference to the topic itself. This approach, which I called this "self-reference", seemed to kill two birds with one stone. But this means that "self-referencing" is only of interest in the context of PSIs (not PS Docs, which is where you have it), when topic maps are used to represent the PSI set. I think self-referencing also relates to the question you raised earlier about whether it makes sense for a topic that is used as a PSI to both reify and indicate the same subject. I think this does make sense, but again, it's only an issue if we represent PSI sets as topic maps. If we don't, it pretty much goes away. So I don't see the point of your proposal for distinguishing between three classes of PSIs.
