==Overview==
{{see|Help:Footnotes}}
A footnote used multiple times may be defined with a name:
:{{tag|ref|params=name="foo"|content=''content''}}

To invoke a named footnote:
:{{tag|ref|s|params=name="foo"}}

References may also be defined within the reference list:

{{pre|<nowiki>
{{reflist|refs=
<ref name=refname1>refcontent1</ref>
<ref name=refname2>refcontent2</ref>
<ref name=refname3>refcontent3</ref>
<ref name=refname4>refcontent4</ref>
}}</nowiki>}}

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

An explanatory note may include a reference by using #tag:ref:
:<code>&#123;&#123;#tag:ref|''refcontent''|name=''name''|group=''groupname''}}</code>

Where ''content'' may include {{tag|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 {{tlx|refn}} or #tag:ref within list defined references. You can only use {{tlx|refn}} or #tag:ref once as a list-defined reference.

==Examples==
{{Help:Cite errors/lang}}

{{xt|In the example below, a reference with the name ''excepteur'' is not named in the References list, since that reference is malformed. This causes a secondary error because the undefined reference is invoked in the References list:}}
