Overview
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
A footnote used multiple times may be defined with a name:
<ref name="foo">content</ref>
To invoke a named footnote:
<ref name="foo" />
References may also be defined within the reference list:
{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2>refcontent2</ref>
<ref name=rename3>refcontent3</ref>
<ref name=rename4>refcontent4</ref>
}}
List-defined references may be invoked by the standard markup or by use of {{r}}.
Issues and resolution
All references defined in the reference list must be invoked in the content. Unused references must be removed or commented out.
Including more than one nested reference in List-defined references will cause a Cite error.
Misusing a template that was never intended as a citation template and placing it in <ref> tags may cause this issue.
A template that creates <ref> tags; known instances:
- {{Certification Cite Ref}}
- {{sfn}} and variants
- {{Singlechart}}
A template that includes table markup; known instances:
