--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.
