Sure, you have some good support there, but it kind of forces the users
to choose between an explicit MVC style vs JAX-RS style, example, you
can't have a Book returned with Produces set to text/xml & text/html.

May be I'm wrong though. But I'd prefer for users to have an option to
have the data to HTML binding done under the hood - I guess though we
may not need to do anything at all for the latter, it works right now
for us via a basic MBW
