  <iframe sandbox="allow-scripts" src="..."></iframe>

where ... is some page that does an XMLHttpRequest to the a page that is same origin with the page that contains the <iframe>. (The page being fetched will have to specify Access-Control-Allow-Origin:* as the request is coming from a unique origin by virtue of the sandbox attribute. The request will include an Origin header but the value will always be null.)

Also, if the document="" or some such attribute is introduced the code will no longer have to be on a separate page.
