Try searching under "correspondence" and "letters", which is the context in
which it most often arises.

I can see a problem as far as correspondence and related issues goes
(especially postscripts) but I don't see one in this example. If the second
lot of stuff truly doesn't belong to the previous or the following div, then
it appears to belong in a div of its own, so why not give it one?  This
looks to me more like a problem of document analysis rather than a tagset
issue.
