Module:Footnotes/whitelist/doc explained

This page is a formatted list of anchor IDs and associated citation wrapper-templates. Because of, short-cite templates, via, will emit false-positive error messages for citation wrapper-templates. The anchor IDs listed here instruct Module:Footnotes to suppress error messages for short-cite templates that link to the anchor IDs listed here so long as the associated citation wrapper-template is present in the article. This is an imperfect system that will allow false-negatives because this mechanism will suppress valid error messages in the absence of a full-cite target. Adding an anchor ID and matching template to this list will suppress all error messages for that anchor ID / template pair.

Do not include disambiguation letters in whitelist entries. In other words, use "CITEREFSmith2018" in this whitelist even when the cite template generates "CITEREFSmith2018a".
