If a browser access a resource, some browsers (e.g. IE 7, FF 2) will
request XML with a higher priority than HTML. Not fine, but it's the
reality. So I think for GET (inclusive HEAD), OPTIONS and other safe
methods it is good.

So my opinion:

    * First preference: define it only for safe methods, remove for
      unsafe methods (safe methods could be defined to be safe by an
      additional attribute to @HttpMethod).
    * Otherwise throw it fully away. It's not a big problem for me;
      Restlet has a solution for it ...
