For the sake of https://www.mediawiki.org/wiki/Help:Extension:Translate/Unstructured_element_translation , Commons has:
```
if ( $wgDBname === 'commonswiki' ) {
$wgHooks['TranslatePostInitGroups'][] = function ( &$cc ) {
$id = 'wiki-translatable';
$mg = new WikiMessageGroup( $id, 'translatable-messages' );
$mg->setLabel( 'Interface' );
$mg->setDescription( 'Messages used in the custom interface of this wiki' );
$cc[$id] = $mg;
return true;
};
};
```
Steinsplitter asked if edits by non admins like https://commons.wikimedia.org/w/index.php?title=MediaWiki:Linkshere/bn&curid=37258716&diff=142454364&oldid=142454323 (which has [[https://commons.wikimedia.org/w/index.php?title=Special:Log&offset=20141212233000&type=translationreview&limit=1|an associated review]] by the same user), or https://commons.wikimedia.org/w/index.php?title=MediaWiki:Linkshere/it&curid=28615533&diff=142322825&oldid=124453994 , are expected behaviour.
Only messages listed in https://commons.wikimedia.org/wiki/MediaWiki:Translatable-messages can be edited, and those don't look problematic, but double checking that they don't alow raw HTML doesn't harm.
