== Usage ==
This is a meta-template; it should only be used within other templates. It is used for [[Wikipedia:Namespace|namespace]] detection as a simplification of <code><nowiki>{{Foo other|Example|{{Incorrect namespace|foo}}}}</nowiki></code>.  If the template is transcluded in the Foo namespace, it will transclude "Example"; if not, it will transclude {{tl|Incorrect namespace}}. Note that {{tl|Incorrect namespace}} does not work in the template namespace.

The first parameter is necessary. It defines which namespace is the correct namespace for the template.

The second parameter is optional. It allows something (usually a category) to be transcluded in the correct namespace.

== Examples ==

=== Correct namespace ===
<code><nowiki>{{Single namespace|Template|This text is only displayed in the Template namespace}}</nowiki></code>

{{Single namespace|Template|This text is only displayed in the Template namespace}}

=== Incorrect namespace ===
<code><nowiki>{{Single namespace|Category|This text is only displayed in the Category namespace}}</nowiki></code>

<!--not using actual template because {{Incorrect namespace}} won't display in the Template namespace-->
{{Mbox | type = content | image = [[File:Stop hand orange.svg|50px]] | text = {{Error|The above template should only be transcluded in the ''Category'' namespace(s).}} }}
