Correspondence: Coding Postscripts in Multiple Hands?

Dear TEI List,
On the Digital Mitford project's coding of correspondence, we're running
into multiple instances in which two different people are writing
postscripts on a letter. Or rather, a second person comes and dashes off a
quick but multi-paragraph note on a letter after the main writer (Mitford)
has finished writing. We want to code these brief messages from other hands
using either <add hand="#soAndSo"><p>...</p></add> or with a properly
placed <handShift/> element, but we're running into troubles because these
aren't permitted inside a <postScript> element. Also, we can't put @hand on
<postScript>.

Okay, we could modify our project schema to permit these elements where we
want them, but we want to follow the recommendations of the Correspondence
SIG. We found this example, which seems just exactly to capture what we're
doing:
http://wiki.tei-c.org/index.php/C._M._v._Weber_an_Johann_G%C3%A4nsbacher,_Berlin,_29th_February_1812

However, the sample TEI encoding of the text appears to be missing. Any
help here?

Thanks,
Elisa
