Template:Citation Style documentation/deprecated

The {{#ifeq:Template||Template:FormattingError|coauthor}} and {{#ifeq:Template||Template:FormattingError|coauthors}} parameters are deprecated. Their use will place the page into Category:Pages containing cite templates with deprecated parameters. Use {{#ifeq:Template||Template:FormattingError|last#}} / {{#ifeq:Template||Template:FormattingError|first#}} or {{#ifeq:Template||Template:FormattingError|author}} or {{#ifeq:Template||Template:FormattingError|authors}}. If {{#ifeq:Template||Template:FormattingError|coauthor · coauthors}} are used for et al, then use {{#ifeq:Template||Template:FormattingError|display-authors=etal}} instead.
