Overview

Further information: Help:Footnotes

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>
}}

List-defined reference may be within groups:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2 groupname=groupname>refcontent2</ref>
}}

List-defined references may be invoked by the standard markup or by use of {{r}}.

Tracked in Phabricator
Task T22707

Note: It is possible to get this error message when nesting footnotes in list-defined references, unfortunately the only fix in this situation is to not use list-defined references for entries that are nested.

Issues and resolution

• A list-defined reference uses a group name that is not used within any <ref>...</ref> tags.
• An explanatory note template such as {{efn}} is used inside <ref>...</ref> tags; use {{refn}} instead of <ref>...</ref> tags.
• Footnotes are nested inside list-defined references. This is a known bug, for now just do not use list-defined references.

Examples

The reference list has a defined reference with a group named note, but there is no reference in the content with that group and name.
