I'm having a hard time seeing it that way. The xml:id circle shows
which profiles appeal to the processing described by an additional
specification. We'd have factored xml:base processing out in a similar
way, I suspect, if we'd been willing to consider a profile that
doesn't mandate it.

The outer-most circle could be removed, I suppose, since it's
universal over our profiles. But I don't find it confusing.

The property of being an "ID" requires the Extended and Decl classes,
I think. I don't think we need a new class, but I could be confused.

                                        Be seeing you,
                                          norm
