I don't believe any browsers implement this yet. But a new MIME type
specifically for sandboxed HTML content seems like the wrong way to go.

As it stands currently, only text/html has a sandboxed equivelant. What about
image/svg+xml, or application/xhtml+xml? Do we really want to make a new fully
qualified sandboxed MIME type for every existing type? They wouldn't really be
new "types." Rather, they look/feel/smell like existing types with the caveat
of setting a single flag.

Instead, a MIME type attribute would be better (ex:  text/html;sandboxed  or
application/xhtml+xml;sandboxed). This would allow any existing (or future)
MIME types to be sandboxed with the unique origin flag.
