This new template should be discussed on its talk page to explain its purpose and build consensus for usage on the site. Until there is a consensus to keep the template it should not be added to more than one low-visibility article (as an example of usage). Please see the template policy for guidelines on when templates are appropriate.
Please do not remove this tag until a consensus to do so has been reached on the article/template's discussion page.
This is an experimental template for a proposed new page class for Gallery pages which are sub-articles to reduce bandwidth of the main article.
