This template is not used directly, it is called by template:UseTOC. It uses a common information store in template:UseTOC to provide the appropriate "forward" and "back" links automatically. On any appropriate wiki page, the navigation header effectively overlays the page name, while a duplicate page name is placed below. It is entirely transparent with regard to localization except for the word and phrase templates used. The contents box is forced to appear in all pages that contain at least one header and is placed toThis the left beneath the line of the page name. The home/index link should be modified within the Template:NavHeaderMiddle itself. Missing or malformed link info defaults to a Navigation Header error page while properly formed but links to missing pages are added to the Special:wanted pages list.
