This is a documentation subpage for Template:Role.|
It contains usage information, categories and other content that is not part of the original template page.
|It has been proposed that this page be deleted or replaced by a redirect. See the discussion page for further information.
The given reason is: While Role exist both in API and at relation pages, it is hard to use in wiki content organisation, even mainpage Role just redirects to Relation this is not coincidence.
