I can't understand details of this talk, but if you like take a look to the raw code of any ns0 page into it.wikisource and consider that "area dati" is removed from wikitext as soon as an user opens the page in edit mode, and re-builded as the user saves it; or take a look here: http://it.wikisource.org/wiki/MediaWiki:Variabili.js where date used into automation/help of edit are collected as js objects.
