Created attachment 11435 [details] This is what the message looks like when visitors see it. (It disappears if one is logged in.) Originally posted on May 11, 2012 at <a href="http://www.referata.com/wiki/User_talk:Yaron_Koren">Yaron Koren's talk page</a> on <a href="http://www.referata.com">Referata</a>. ---- I've already customised a handful of system messages on <a href="http://sevton.referata.com">WikiSevton</a> relating to the SMW system. But one of them, <a href="http://sevton.referata.com/wiki/MediaWiki:Anoneditwarning">Anoneditwarning</a>, is now irking me the most. Though it displays correctly on edit forms like <a href="http://sevton.referata.com/w/index.php?title=Diane&action=edit">this one</a> (when viewed by visitors), the wikilinks and external links will refuse to do so in <a href="http://sevton.referata.com/wiki/Special:FormEdit/Character/Diane">this semantic form</a>. Though I've tried getting around it with several parser tweaks, and looking at the page's source code with IE's F12 tools, I don't understand why all that raw code must taint the page. I really don't know why. Can you give an explanation (and hopefully a solution)? (Version: MW 1.19.2; SMW 1.8 beta 2. Browsers: IE/Chrome [and possibly several others as well].)
Created attachment 11450 [details] This is how it appears on normal edit forms.
Created attachment 11555 [details] A modified version of the standard message using regular HTML formatting. Note the <a> links, which are NOT allowed in MediaWiki.
Created attachment 13232 [details] This also happens with MediaWiki:Smw_types_docu on Special:Types.
Messages are generally sanitized to shield against possible XSS attacks. Those messages seen on special pages need an appropriate escaping method to allow raw HTML being displayed as formatted text. Adopting system messages (more specifically SMW messages) that inject raw HTML is in most cases not permitted [1] and will result in messages being displayed as "clear" string due to the sanitization process.
