This requires more fine grained control of what is user generated content and what is scripted content. The problem is 1: that the user can easily write </span> in his comment and bypass the sandbox and 2: it is not backward compatible. This is prevented by requiring anything inside a sandbox being entity escaped: <span sandbox=1> &lt;/span&gt; </span> If the browser finds unescaped content inside a sandbox it should refuse to display the page - thereby forcing the author to fix this immediately. Any comments? </pre> </div> <div class="msgButtons margintopdouble"> <ul class="overflow"> <li class="msgButtonItems"><a class="button buttonleft " accesskey="p" href="msg10456.html">Previous message</a></li> <li class="msgButtonItems textaligncenter"><a class="button" accesskey="c" href="index.html#10459">View by thread</a></li> <li class="msgButtonItems textaligncenter"><a class="button" accesskey="i" href="maillist.html#10459">View by date</a></li> <li class="msgButtonItems textalignright"><a class="button buttonright " accesskey="n" href="msg10460.html">Next message</a></li> </ul> </div> <a name="tslice"></a> <div class="tSliceList margintopdouble"> <ul class="icons monospace"> <li class="icons-email tSliceCur"><span class="subject">[whatwg] The <iframe> element and sandboxing ide...</span> <span class="sender italic">Frode Børli</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg10460.html">Re: [whatwg] The <iframe> element and sandb...</a></span> <span class="sender italic">James Ide</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg10476.html">Re: [whatwg] The <iframe> element and s...</a></span> <span class="sender italic">Frode Børli</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg10480.html">Re: [whatwg] The <iframe> element a...</a></span> <span class="sender italic">James Ide</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg10484.html">Re: [whatwg] The <iframe> eleme...</a></span> <span class="sender italic">Frode Børli</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg10485.html">Re: [whatwg] The <iframe> ...</a></span> <span class="sender italic">Edward Z.
