I want to use a slightly modified version of the DITA XSL-FO stylesheets used for on-screen rendering. So far, I've done this simply by modifying the relevant file in $SERNA_INSTALLATION_DIR/plugins/dita/dita-xsl-serna/, but I don't like modifying the application directory if I don't have to. I know that there is a way to add directories to the plugin path, but it looks like the added directories are searched after the one in the main installation directory.

Is there any way to have Serna XML editor use a local plugin for DITA that overrides the one in $SERNA_INSTALLATION_DIR?
