here you could delete the StartBookpart, or better after
(if thetitle
further test for (zero? (string-length thetitle))
and delete it if the title is an empty string rather than creating it.

here, you could remove the EndBookpart if it is already present
making it a toggle:
(if (d-Directive-movementcontrol? tag)
(d-DirectiveDelete-movemencontrol tag)
(begin
;; or create it if it doesn't exist

with all these refinements you can give feedback about what you have
done (deleting, setting) via d-InfoDialog or the timed notice routine
that doesn't require the user to respond.
