WHATWG Weekly: Mutation Observers, and oh, XBL is dead!
Philip Jägenstedt provided feedback on WebVTT based on a meeting between various browsers at the Open Video Conference. Tyler Close raised two security issues with registerProtocolHandler(). This is the WHATWG Weekly.
Changes to HTML
Since revision 6596 the specification defines handling of multipart/x-mixed-replace resources. A rather peculiar MIME type that allows progressively updating of content. Revision 6595 states that ins and del are not ideal for marking up edits to tables. This should come as a surprise to exactly nobody.
Mutation Observers
Adam Klein has outlined the latest proposal to replace Mutation Events on the WebApps WG mailing list: Mutation Observers. While some of the details are still being discussed, it seems this proposal has a better chance at succeeding than previous proposals due to the support of a number of developers from both Mozilla and Google.
According to Wikipedia (http://en.wikipedia.org/wiki/MIME#Mixed-Replace_.28experimental.29), this is an experimental MIME Type (Internet Media Type). I just didn’t understand. Are you pushing this MIME Type to become a standard and get out of being experimental, or are you simply remove it? Not very clear in that second paragraph.
It is being standardized by HTML. Mind you, we cannot remove the experimental prefix.
