{{Documentation subpage}}
This template handles '''the "error-messages" for {{tl|Infobox isotopes (meta)}}''' and derived pages like {{tl|Isotopes/main/table}}, {{tl|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:
*{{cl|Isotope template issues|Category:Isotope template ''issues''}} -- aka "errors", affects Article. To be handled (fixed). Preview-warnings in mainspace.
*{{cl|Isotope template trackings|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):<sup><span style="background: gold">[[:category:Isotope template trackings|cat:]]<nowiki>#A</nowiki></span></sup>
* [[:module:Check for unknown parameters|checkFUP]] ('Check for unknown parameters', the classical method): preview warning, categorise mainspace article.

===Unknown parameters===
Unknown parameters are checked by [[:Module:Check for unknown parameters]] ([[WP:CFUP]], checkfup)
Mainspace pages are categorised in {{clc|Isotope template issues|pages}}, under "U".
That is, a single error will list twice (say, by articles [[polonium]], [[Isotopes of polonium]]).

===pagetypes===
:Pagetype detection
::{{code|1=ns-main, ns-template, ns-other}}
::{{code|1=rootpage, subpage}}
::{{code|1=isotope-page}} has "isotope" in pagename? 
::{{code|1=meta, not-meta, }} is meta template? 
::{{code|1=msgclass-issue, msgclass-tracked, }} msg-type (from {{para|catsort}})

Action is determined by AND-checking ppagetypes:

<syntaxhighlight lang="wikitext">
|11-action-preview-show-AND        =msgclass-issue
|12-action-preview-show-AND        =msgclass-tracked
|21-action-catlink-write-persistent-AND =ns-template, isotope-page, testcases
|31-action-categorise-write-AND    =ns-main, msgclass-issue
|32-action-categorise-write-AND    =ns-template, msgclass-issue, isotope-page, rootpage, not-meta
|36-action-categorise-write-AND    =ns-template, msgclass-tracked, isotope-page, rootpage, not-meta
</syntaxhighlight>

This property-string (csv) is checked by {{tl|str find word}} ("if page-types has 'ns-template, rootpage, not-meta' then categorise")
