Thread:Extension talk:Babel/Localisation

I am a translator on translatewiki.net and trying to write documentation for the Babel extension messages. On MediaWiki:Babel-autocreate-text-main, could someone let me know whether the variable $1 is the name or the number of a skill level. Also, I assume that this message is the text of a category page. But this text is not appearing on translatewiki.net so I can't check this out.
