* Defines the media type(s) that the methods of a resource class or
* {@link javax.ws.rs.ext.MessageBodyWriter} can produce.
* If not specified then a container will assume that any type can be produced.
* Method level annotations override a class level annotation. A container
* is responsible for ensuring that the method invoked is capable of producing
* one of the media types requested in the HTTP request. If no such method is
* available the container must respond with a HTTP "406 Not Acceptable" as
* specified by RFC 2616.
*
* A method for which there is a single-valued {@code @Produces}
* is not required to set the media type of representations that it produces:
* the container will use the value of the {@code @Produces} when
* sending a response.
