Naturally, this produces bad HTML. Pages in the MediaWiki namespace may stop working if extra HTML is added.
Is this report specifically about the broken iu 'copyrightwarning' message? If so, see http://iu.wikipedia.org/w/index.php?title=MediaWiki:Copyrightwarning&action=edit and compare it to the same message in other wikis. The message can only be changed by the sysop for iu.wikipedia.org.
Well, yes. The message was broken by a recent code change, and had worked fairly well previously. Another issue here is the second-class status of 'plainlinks', which has no system message of its own and must be attached to the copyright warning.
