Is it possible to reference query parameter to enum defined in definitions ?

Is it possible to reference query parameter to enum defined in definitions ? For example consider following example:

paths:
  /users/test:
    get:
      summary: Test endpoint
      parameters:
        - name: osType
          in: query
          description: Client's OS type.
          required: true
          type: string
          enum:
          - ios
          - android

then I define this

definitions:
  OsTypes:
    type: string
    enum:
    - ios
    - android

Can I reference it from endpoint to avoid defining allowed values of the enum in every endpoint that uses it ?

I tried

schema:
  $ref: '#/definitions/OsTypes'

Thanks!

There's currently no way to reference definitions that are not body parameters. We're definitely considering changing that in a future version, which is covered by #301.
