If you only knew a tag that would magically fix all the security issues in IE6 :)

Well, there is the "PLAINTEXT" tag[1], but I don't know if that will actually get all of IE6's security issues, even if you put it at the very start of the document.

The attributes for it are pretty weird, too. Why would you put language="javascript" inside such a tag?
