One item in a bibliographic list
A <ref> is typically a citation describing a referenced work (see Tagging References). This Tag Set allows notes as well as citations in a bibliographic list, but best practice is to place notes in an <fn-group> or <notes> section and use <ref-list> only for bibliographic citations.
