Category:Template implementation details

This category is intended to collect all "devices" (often templates themselves) that are internal implementation details of Wikipedia templates. These are not meant to be directly used by regular editors. They are sub-templates organized by a rootname of the primary template grouped in one place for the benefit of template implementors.
This is, by the way, the reason why they are provided with very little external documentation.

The pages listed in this category are templates.

This page is part of Wikipedia's administration and not part of the encyclopedia.

Further template category notes

This category contains pages in the template namespace. It should not be used to categorize articles or pages in other namespaces.

To add a template to this category:

If the template has a separate documentation page (usually called "Template:template name/doc"), add
[[Category:Template implementation details]]
to the <includeonly> section at the bottom of that page. Otherwise, add
<noinclude>[[Category:Template implementation details]]</noinclude>
to the end of the template code, making sure it starts on the same line as the code's last character.
