print run of book

Dear list,

does the TEI offer an element to describe the print run of a book? Besides
the number of copies of one book, I also want to specify the copy which I
use for my edition (the number of the specific copy is given in the
imprimatur). What would you suggest?

At the moment I am capturing this information in <biblFull> in the
<editionStmt>:

              <editionStmt>
                 <edition n="1">copies 300, copy n.192</edition>
              </editionStmt>

This snippet should express: First edition, total number of copies 300, of
which copy 192 is used.

Is this the right way or is there a more elegant solution which I've
overlooked?

Thanks a lot,
Frederike
