Are notes and examples in the core language specification of the C++ Standard non-normative?

Question

Often on SO (and elsewhere) I have seen the claim that notes and examples in the C++ Standard are not normative - I have probably made this claim myself a few times

Answer 1

This is generic for all ISO standard documents:

An example integrated in the text of a document, used for giving additional information intended to assist the understanding or use of the document. In ISO standards, examples are without exception non-normative.

A similar clause applies to notes:

A note integrated in the text of a document, used for giving additional information intended to assist the understanding or use of the document. In ISO standards, notes are without exception non-normative.
