Is this intentional? It seems to me that we either want a parameter for text/html or a new element. Also: do we care about sandboxed XHTML or SVG? 31061 1 w3c 2010-01-15 00:32:12 +0000 The back-compat story for text/sandboxed-html is that the media type triggers a download in legacy UAs, which is safe. @sandbox purposefully defaults to open in old UAs. That's so that folks can deploy @sandbox for defense in depth on existing web properties. By combining the two, you can get a fail-safe behavior in old UAs for @sandbox. 31879 2 ian 2010-02-13 04:01:53 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.

For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Rejected Change Description: no spec change Rationale: What Adam said. I have no opinion on whether XML should be sandboxed; that seems out of scope for this group. (If the XML or SVG groups want HTML5 to define a sandboxed type for them, I'm happy to oblige, of course. I just don't want to step on toes when it's not necessary for getting interop on existing features.)
