Replace "fat" XML responses with modern JSON/RESTful responses

[Quix0r]

JSF seem to be criticized for having XML responses in AJAX requests. Those come from an older time of the JSF specification (as I know) and are today out-dated to use XML in HTTP responses. Modern MVC frameworks (like JSF is) use JSONs or RESTful responses (I know the former one).

This proposed change will drastically reduce the utilized bandwidth and "silence" critics directing this issue. :-)

It's perhaps not always so super clear cut due to compression (XML compresses really well), but nevertheless a JSON response is absolutely in scope. I remember we discussed this before, but it didn't make the 2.2 or 2.3 cut.

JSF/PF are being criticized for having "fat" XML responses in AJAX responses. Sure you cannot make everything right for everybody. So let's bring it back and (maybe) assign it to 2.4 or 2.5 specification.

Of course, PrimeFaces are not the topic here, just mentioned it. I may have to bring it up over there, too then.
