Hi Susan,
So sorry for the delay! I was "waiting" for you to post the print, thinking I would be automatically notified. Not so, and I should have manually checked.
This involves formatting, which means Braille Formats trumps UEB. Follow the BF guidelines and samples, brailling the poem twice with the stress and unstressed marks above the second transcription, with a transcriber's note explaining.
Braille on,
Julie
