AsyncApi mark channel as deprecated

I am currently working on my API documentation with AsyncApi. I couldn't find an example of marking a channel as deprecated, does anyone know how to do that? I tried it as follow, but there is no visible sign that the channel is deprecated when accessing the api.

channels:
  queuing.XXX:
    description: >
      ....
    publish:
      message:
        oneOf:
          - name: XXX
            description: >
              ...
            deprecated: true
            payload:
              $ref: '#/components/schemas/XXX'
...

Solution

In current AsyncAPI Specification (at the time of writing - for version 2.4.0) you can use only deprecated keyword in the Schema Object. If you think that deprecation of Message Object (like in your example) or Channel/Operation Object should be allowed in spec, you can create issue for that https://github.com/asyncapi/spec/issues or even crate proposal for newer versions of spec.

You can check how spec looks like here https://github.com/asyncapi/spec/blob/master/spec/asyncapi.md
