[oXygen-user] Preventing oXygen XML Author/Editor from overwriting commonltr.css?

Hi group I generate XHTML from my ditamap. In this process, the commonltr.css file in the OXYGEN_INSTALL_DIR\frameworks\dita\DITA-OT\resource\ folder gets copied to the output directory. However, I'd like to use a customized commonltr.css file in the output folder, but keep the original commonltr.css file in the OXYGEN_INSTALL_DIR\frameworks\dita\DITA-OT\resource\ folder. Is there an elegant way to do this? When I regenerate output, I see that the commonltr.css file in the output folder is overwritten. Thanks. -- Yves Barbion www.scripto.nu
