rule: produce/consume absence should be signaled

[XVincentX]

If I have this document where there's no global nor local produce:

swagger: '2.0'
paths:
  /path:
    post:
      consumes:
        - application/json
      parameters:
        - in: body
          name: body
          schema:
            type: object
            properties:
              id:
                type: integer
              status:
                type: string
                enum:
                  - open
                  - close
            required:
              - id
      responses:
        200:
          schema:
            type: string

I'd be expecting an error
