Part of

I have removed the mandatory "item requires statement constraint" for "part of: Linked Open Data cloud diagram". These data set are described by that diagram, but are not part of it, any more than Tim Berners-Lee is part of the English Wikipedia, because it has an article describing him. For the same reason, I think that such statements should have a constraint deprecating them, and should be removed.
