Re: [xml-dev] The Exchange of Information

Hi Roger,

I always appreciate your attempts to look for analogies and neat ways to
communicate sometimes difficult topics, but you need to be warned that
what you've sketched is a blissfully naive and totally obsolete view of
communication and the human language faculty. I suggest you chuck that
book away and get something recent instead :-)

And if you persist by using the analogy (you've sent something along
these lines only a few months ago, after all), I advise you to make sure
to indicate to the reader that the first picture is only simplistic, or
else you risk losing the reader's confidence right after that first

Best regards,
