This would be my preference, have standard attributes (as defined in
RFC) supported explicitly, the parameters map is there to accommodate
for the extensions if any.

it does not harm but as I said I can see it working with the 'consumes'
extension together, with the idea being that knowing the method and what
the 'target' accepts, one can post/put to it.

I'd drop the explicit support for 'produces', and either keep the
explicit support for consumes + method or drop both. If we were to keep
them then I'd also rename 'consumes' to 'accept' to give it a more
JAX-RS-neutral name
