SNS bindings questions

[rospe]

Hi all,

one question regarding the SNS binding in AsyncAPI 3.0.0.

When I use

    bindings:
      sns: #(required) if using SNS
        name: mySNSTopic

in my channel definition, wouldn't name now refer to the channel address? An if that's the same, can I just omit it?

And then one question regarding SNS Filter Policies: as an event producer, how can I let my consumers know which filter keywords and values to use when they just want to consume a subset of the messages published on a topic?
And would this information belong to an operations binding or somewhere else? I do not intend to add the consumers themselves to the asyncapi document at this point in time.

Thanks!
