{#- Admin form to add or edit an edition.

   typed holds what a refused save sent, when the view shows the form again
   with the reason flashed above it, so the fields keep what was typed
   instead of what is stored. The controls the form locks keep showing what
   is stored. Without typed the fields show the stored edition.
