I am sorry, I strongly disagree with that. The current text is misleading for the casual reader of our spec (who will strongly rely on the examples) and giving a wrong impression via examples is a source of trouble. I do not see any consistency issue here, and even if there was, I would disagree with that argument.

_Something_ should be said in the examples that people should not rely on the bnode identifiers. I fully trust Shane to find the best editorial approach. But the current text is not acceptable in my view.
