sorry for not understanding your point.  there is no backward compatible
way forward for 8805.  so i have hacked as you suggest

        The appendix MUST be 'hidden' as a series of "#" comments at the
        end of the geofeed file.  The following is a cryptographically
        incorrect, albeit simple example.  A correct and full example is
        in <xref target="example"/>.
