Yes.
All RFC 821 examples use TLD .arpa, s/.arpa/.example/g in RFC 821 could work.
IMO: Not at all. Examples should be realistic, in the sense that they
remind readers of the real thing. "foo.example" doesn't strike me as a
good example of a fully-qualified domain name. ("foo.arpa" isn't too
good either, now that .arpa is long forgotten.)
Maybe you tried your exampl-ification later, not based on RFC 821 (?)
I looked it up: The place that made me give up is 2821 appendix D.
