This is the {{pp-template}} protection notice.

It is used on protected templates and on protected file (image) pages.

Please note that only administrators can protect pages, this template only informs about the protection status of the page.

When {{pp-template}} is added to a protected template, it should be placed inside tags <noinclude></noinclude> (otherwise, every page which uses the template will load the protection notice, which will result in an error message).
