Template:Isotopes/main/error-message/doc

This is a documentation subpage for Template:Isotopes/main/error-message. It may contain usage information, categories and other content that is not part of the original template page.

This template handles the "error-messages" for {{Infobox isotopes (meta)}} and derived pages like {{Isotopes/main/table}}, {{Isotopes/main/isotope}}. "Error-messages" is to be read as: issues, tracking, page categorising: all actions and notifications that do not belong in the Article content.

Two maintenance categories are populated:

• Category:Isotope template issues -- aka "errors", affects Article. To be handled (fixed). Preview-warnings in mainspace.
• Category:Isotope template trackings -- passive listing, nothing to repair but good to follow.

Messaging and categorisation is by various page-properties.

• "Error" issues, to be fixed: preview warning, categorise page(s)
• Tracked issues: not preview warned in mainspace; only template page is categorised (the instance not the meta; not the article). Extra indicator permanmanently visible in any template subpage (like /testcases, /sandbox):^cat:#A
• checkFUP ('Check for unknown parameters', the classical method): preview warning, categorise mainspace article.
