For example, RFC-822 implementations which expect the BNF

which you use to generate RFC-822 and another which you use
to parse.  The same thing is happening now with MIME, in
spite of my (evidentally futile) attempts to nip it in the

The old saw of `be liberal in what you accept, be
conservative in what you generate' hides a great many sins.
