The glossary is one place to start making this distinction.  It
currently has entries for "argument," "positional argument," and
"keyword argument" that could perhaps use a review from this
discussion.  For example:

http://docs.python.org/dev/glossary.html#term-positional-argument

The entries currently blur the distinction between the calling and
definition perspectives.  Ideally, the glossary definitions of these
terms would match and be consistent with their usage in error
messages.
