The available MIME types for a REST API descriptor. The MIME types specified in the preference determine the contents of the Consumes and Produces fields in the REST API Descriptor wizard, on the General tab in the REST API descriptor editor, and for an operation on the REST Resources tab. You can add, edit, or remove MIME types. You can also restore the list of available MIME types to the default list.
