Template:Namespace link/doc

Usage
For use in the  namespace. In  and   namespaces no effect, while in other namespaces provides a link to the subpage, or subpage#anchor (if #anchor provided) of the current page in the main namespace. For similar functionality but without the use of subpages, see.

Note
With the use of the template, if the links are internal to the transcluded work itself, and relative to pages, then relative links can be used to refer to a work, rather than the requirement for name of the work ie.
