I assume, that your match may fixed a issue caused by xemacs.

So, I would to prefer, that the user should make a update to the specific
release of xemacs on which the issue doesn't occurs.

You may write someting link

# You need xemacs >= <required release> to
# fix the following issue ...
Requires:    xemacs >= <required release>


Of corse, if the required release may not available on older
distribution, you may embrace the Requires statement into
a condition.
