Hi, I like use sgml and try to install it on fedora, I have psgml, openjade, opensd, linuxdoc, but I don't have sgml-data, sgml-base, sgml-tools (I didn't found any package for fedora-core) In Emacs after typing <!doctype linuxdoc system> with shift and right button of the mouse I can have <linuxdoc></linuxdoc> And that's all, after i have a bip with this message "External entity LINUXDOC not found" I don't understand what is going wrong ?? Could you help me Hervaen
