return z - --NOTES -- -- NOTE A1: This Lua module was originally designed to handle a mix --     of citation styles, crossing Vancouver style with Wikipedia's --      local Citation Style 1 (CS1) from {Template:Citation/core}. --     However, the conflicting positions of parameters, scattered --     in twisted locations across this module, led to a separate --     variation just to untangle the CS1 format of citations. -- -- NOTE D2: The placement of dots and other separators between the --     displayed parameters has been a continual headache, to keep --     coordinated with the data in parentheses "(data)". There --     has been a need to pre-check for the existence of related --     options, to keep from putting double-dots ".." in some cases. --     In particular, the omission of the "title=" parameter has led --     to several cases of a spurious dot ". ." because the original --     design had treated the title as a mandatory parameter. --
