It is used to build and maintain a list or lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of theencyclopedia's categorization scheme.
These categories are used to track, build and organize lists of pages needing "attentionen 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 subcategories into a larger, more efficient list (discriminated by classifications).
Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (seeSpecial:TrackingCategories for an overview of the latter).

This is a non-error tracking category for{{Taxonbar}} templates which use multiple Wikidata items (also referred to as 'entities' or 'QIDs') via multiple|from#= parameters.
Many articles which use{{Taxonbar}} will only use the|from=/|from1= parameter, since only a single relevant Wikidata item exists. However, Wikidata items relate to taxonnames rather thantaxa. So, when severalsynonyms are in common use and taxonomic databases contain relevant information under these synonyms, multiple|from#= parameters are appropriate. This category is a repository for those cases; for example,Aeonium aureum.
Pages in this category should only be added byModule:Taxonbar.
