There is no need for a manual to have any invariant sections. The simplest case is to have none at all. You do not have to list the GNU FDL itself as an invariant section, because the FDL explicitly says that the FDL itself may not be changed. The FDL also distinguishes certain section titles, &ldquo;History&rdquo; and &ldquo;Dedications&rdquo; and others. You should not list these sections as invariant, because the FDL already gives the rules for these sections.
