Overview

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=refname1>refcontent1</ref>
<ref name=refname2>refcontent2</ref>
<ref name=refname3>refcontent3</ref>
<ref name=refname4>refcontent4</ref>
}}

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

An explanatory note may include a reference by using #tag:ref:

{{#tag:ref|refcontent|name=name|group=groupname}}

Where content may include <ref>...</ref> tags

Issues and resolution

A list-defined reference has an invalid name. Ensure the footnote name is formatted properly.

More than one use of #tag:ref within list defined references. You can only use #tag:ref once as a list-defined reference.
