== Description ==
It is to indicate whether it can be safely used in citation templates. By default, it indicates the template is safe for use.

When the template is set as "not safe", the page is placed into {{cl|Templates not safe for use in citation templates}}.

== Usage ==
To indicate a template which can be safely used in citation templates: <code><nowiki>{{COinS safe}}</nowiki></code>

To indicate a template that should '''NOT''' be used in citation templates: <code><nowiki>{{COinS safe|n}}</nowiki></code>

To add extra info after the standard message: {{para|addtext}}

== Examples ==
{| class="wikitable"
|-
!style="width: 25%;"| Code !! Result
|-
| {{tlx|COinS safe}} || {{COinS safe}}
|-
| {{tlx|COinS safe|n}} || {{COinS safe|n}}
|-
| {{tlx|COinS safe|addtext{{=}}Here is the extra info.}} || {{COinS safe|addtext=Here is the extra info.}}
|-
| {{tlx|COinS safe|n|addtext{{=}}Here is the extra info.}} || {{COinS safe|n|addtext=Here is the extra info.}}
|}

== Explain COinS issues ==
Citation templates such as {{cs1}} and {{cs2}} generate COinS metadata. If a template is used in a citation template field, then it may inject HTML into the metadata.

Compare the rendered HTML for {{tl|cite book}} with {{para|author}} using no template and using {{tl|smallcaps}}.

{| 
|-
|
{{markup
|<nowiki>{{cite book |author=Sam Drucker |title=Title}}</nowiki>
|{{cite book |author=Sam Drucker |title=Title}}

{{code|{{cite book |author=Sam Drucker |title=Title}}}}

|<nowiki>{{cite book |author={{smallcaps|Sam Drucker}} |title=Title}}</nowiki>
|{{cite book |author={{smallcaps|Sam Drucker}} |title=Title |<!-- adding template-doc-demo in 2018 to remove this page from the error category while preserving the error message --> template-doc-demo=true}}

{{code|{{cite book |author={{smallcaps|Sam Drucker}} |title=Title}}}}
}}
|}

The author metadata is in the {{code|rft.aulast}} field. In this case, it is percent-encoded and is rendered as <code><nowiki><span class="smallcaps" style="font-variant:small-caps;">Sam Drucker</span></nowiki></code>

Reference management software will interpret the entire span as the author name.
