It is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the encyclopedia's categorization scheme.
These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).
This category is used to categorize by the Module:Infobox module.
This category contains pages which use embedded infobox templates which include "title" as a parameter in either the infobox, or in a template called by the infobox.
