> change bars have to be reset every time
I feel a nuance coming on … in an earlier position, I produced goodness knows how many releases of some regulatory documentation; management were delighted that with judicious use of conditionals we could save all the release history in the same file(s). Version 1, new_v1 condition set to display with change bars and deleted_v1 with strikethrough; Version 2, new_v2 with change bars, new_v1 without, deleted_v1 hidden. So I was resetting the conditional text display, but for my own benefit.
A pity that .html-based ouput hasn't caught up with .pdf, though.
