recursion hangs validator, but imho it's a valid spec

[martinrode]

Including a file "schema/config_param.yml" hangs the validator.

I was able to define a recursion in the top level comonents.schema section but not inside an included schema file.

discriminator:
  propertyName: "type"
oneOf:
  - title: "text"
    description: |
      type "text": **text** is a simple string.
    type: object
    required:
      - type
    properties:
      default:
        type: string
      position:
        type: number
        format: int32
        minimum: 0
        description: |
          Position of the parameter in the output.
      name:
        type: string
        description: "name of the parameter as used in the API"
  - title: "table"
    description: |
      type "table"
    type: object
    required:
      - type
    properties:
      default:
        type: string
      position:
        type: number
        format: int32
        minimum: 0
        description: |
          Position of the parameter in the output.
      name:
        type: string
        description: "name of the parameter as used in the API"
      fields:
        type: array
        items:
          $ref: 'config_param.yml'

Using $ref: '#' reports "unresolved ref" which is imho wrong as it should simply include the file again.
