<This kind of solution sounds good, but it defeats the whole purpose of the
document not relying on any SINGLE format! If you manually insert a formatted
footnote, and then have to resubmit your ms. for another publishing format,
you have to do everything over again! What we need is: The ability to insert
a formatted reference at the point of citation.>

One of us doesn't understand the other, or perhaps neither of us understands
the other.  The formatted reference *is* inserted at the point of citation,
by simply clicking on the particular book/journal/catalog or what-have-you in
ENDNOTE after you indicate in WORD where the footnote is to go.  This is not
what I would call "manually" inserting a footnote.

You can have as many different formats, for different publishers, as you like
as long as you give them different names.  If you are submitting the same
manuscript to publishers who use different formats, I see no alternative to
printing it again with a different format.  Since it can be done by pointing
and clicking with minimal writing, however, it doesn't seem terribly onerous.
