Multiple errors for one status code

[v1tam1nb2]

We are expecting multiple error types for a single status code.
Is it possible to express the following Swagger configuration using TypeSpec?

      responses:
        '400':
          description: Bad request
          content:
            application/json:
              schema:
                oneOf:
                  - $ref: '#/components/responses/InvalidFormat'
                  - $ref: '#/components/responses/DuplicatedTitle'
                  - $ref: '#/components/responses/MethodArgumentNotValid'
              examples:
                InvalidFormat:
                  value:
                    status: 400
                    message: XXXXXXX
                DuplicatedTitle:
                  value:
                    status: 400
                    message: XXXXXXXX
                MethodArgumentNotValid:
                  value:
                    status: 400
                    message: XXXXXXX

You can do this

import "@typespec/http";
using Http;

op bad(): Error1 | Error2 | Error3;

@error
model Error {
  @statusCode _: 400;
}
model Error1 is Error {
  error1: string;
}

model Error2 is Error {
  error1: string;
}

model Error3 is Error {
  error1: string;
}

Can Examples be expressed in TypeSpec?

              examples:
                InvalidFormat:
                  value:
                    status: 400
                    message: XXXXXXX
                DuplicatedTitle:
                  value:
                    status: 400
                    message: XXXXXXXX
                MethodArgumentNotValid:
                  value:
                    status: 400
                    message: XXXXXXX

you can but seems like we have a bug where it doesn't show up when you have those multiple response
