Schema Marking Property of a $ref as Required Results in oas-schema-check Error

[sshaw]

Using 0.13.5 with the following:

# ...

schema_a:
  type: object
  properties:
    schema_a_foo:
      type: string

schema_b:
  allOf:
    - $ref: '#/components/schemas/schema_a'
    - type: object
      required:
        - schema_a_foo
        - foo
      properties:
        foo:
          type: string
        bar:
          type: string

Results in an error for schema_a_foo:

`required` field `schema_a_foo` is not defined in `properties`

Is this is correct? We've been using it for sometime without issue and I do see it in Swagger's editor schema_a_foo being marked as required 😅

@sshaw , your structure is correct , it impose that any object following schema_b must have a shema_a_foo field and that it is a string

the issue you are raising is a duplicate of this one
#468

@daveshanley you might close it
