Hello. Thanks for your work but this is not the best place to share it. Translation of Xfce projects is done on Transifex[1]. The right way to contribute translations is described in Xfce documentation[2]. The communication goes on the mailing list[3]. It appears that before your work is included, the translation strings from the man page would have to be extracted, as I don't see them in .po files. Unfortunately, I'm not well versed in l10n, so I'll try pinging upstream for you.
Best, Akbar. [1] https://www.transifex.com/xfce/public [2] https://docs.xfce.org/contribute/translate/start [3] https://mail.xfce.org/mailman/listinfo/xfce-i18n
