This template handles categorization of the current page when no url has been provided for the source citation.
No parameters; behavior is based entirely on the name of the current page. The category, if deployed, is Category:Articles with broken source templates.
Because this is only called when fields
nocat are both blank, it's vastly less heavily transcluded than the parent template, so changes here are relatively inexpensive. At this writing, categorization is done in all namespaces except
Template (thus omitting preload templates) and
User (thus omitting mothballed unpublished articles).
