Template:Translatable template name/doc

Purpose
This template is used to return the name of translatable templates in the language of the current page. Templates, like all other MediaWiki pages, can be translated using the Translate extension, which creates subpages with the form "pagename/language code". The template first checks if the name of the page contains a language code. If it does, it then checks if the template name given as a first parameter has a translation in that language. If the page name does not contain a language code, or if the navigation template doesn't exist in that language, it will display the English template.

How to use


Example (from translatable meta:Template:Meta, used in translatable page meta:Meta:About):


 * or

which returns the translated versions of Tnavbar if it exists, or the English version if translations don't exist.

Parameters
The current version of the template may now include any kind of named or numbered parameters, whose values will be transferred into the called template (with the exception of parameter 1 containing the basename of the translatable template to transclude). Numbered parameters will be shifted down by one position, all named parameters will be passed unchanged.

One named parameter is treated specially: This  will be used to specify another namespace from which the translatable pagename will be transcluded, instead of referencing the page name from the default   namespace. Note that this parameter is also passed (without modification) within the parameters of the transclusion.

Example with one parameters (from meta:Meta:About which is translatable):

Dependency
