Thanks, Cindi! You took the words right out of my mouth. I would also like to point out that UEB updates can be found at this link: http://iceb.org/ueb.html. Nowhere on that page does it say to add TN indicators to the TN page. If it did, as Cindi says, it falls into the domain of formatting, which is governed by individual braille authorities. For us, that's BANA.
Braille on,
Julie
