If you read the PEP carefully, you'd notice that I'm thinking of
docstrings in two related ways: parse time and run time. The parse time
docstring is a superset of the runtime docstring. The runtime docstring
is the memo, the parse time is the book.

I don't believe that is true: as you say, nobody wants to write HTML or
XML or TeX.

Not really: I'm not saying documentation for a module *must be* in the
module, I'm saying the format must be flexible enough for it to be
able to. What people will do is their own business.
In my last proposal after IPC8, there was an elabortate
template/docstring/xml trinity. At the time it was dismissed by Fred
as irrelevant: it seems there are less then 5 people on the face of the
planet interested in documentation outside the modules, so he can
decide on the format himself. I told him I *am* interested, and if
you are, you should tell him so too. In any case, the relationship
between a manual outside and a docstring inside is yet to be defined,
and not by PEP-0216.
Let me just note that as a Perl hacker, the fact that the documentation
(up to and including the tutorial and manual) being *inside* the code
is very convinient. E.g., knowing that "perldoc HTML::Mason" just
works, and gives me everything I need. Indeed POD is a large part
of my inspiration.
