not and $ref is not supported

[jmini]

Take this OAS3 spec:

openapi: 3.0.1
info:
  title: not test
  version: '1.0'
servers:
  - url: 'http://localhost:8000/'
paths:
  /some/ping:
    get:
      operationId: pingOp
      responses:
        '200':
          description: OK
          content:
            text/plain:
              schema:
                $ref: '#/components/schemas/SomeObj'
components:
  schemas:
    SomeObj:
      type: object
      properties:
        other:
          not:
            $ref: '#/components/schemas/OtherObj'
    OtherObj:
      type: string
      enum: [A, B, C]

@jmini , thanks for the bug report! Indeed this seems to be a case where the validation (and content assist) do not allow for a schema reference, only an inline schema.

We'll fix this.

Looks like an issue with the schema. If we look at https://github.com/RepreZen/KaiZen-OpenAPI-Editor/blob/master/com.reprezen.swagedit.openapi3/src/com/reprezen/swagedit/openapi3/schema/schema_v3.json#L822 we see that not references #/definitions/schema. To make that work it should reference #/definitions/schemaOrReference.
