Question for browser implementers:

Currently sandbox is tied to iframe in the spec, is that strictly
necessary? Would it be possible to implement @sandbox in such a way
that it could be used on a div/article/p?

<div sandbox="allow-same-origin">
<p>javascript:x = 3; (x &gt; 5)? "x is less": "x is greater"<br>
should be:<br>
javascript:x = 3; (x &gt; 5)? "x is greater" : "x is less"<br>

>From an authoring/publishing perspective it would be MUCH simpler to
use and deploy. The fall back story is also much better, as older
browsers would still see the content (yes, that's a feature, not a
bug). If something needed to be more heavily sandboxed (only shown if
sandboxed) the iframe model would still work.
