title: How do I specify a "JSON Raw Message" in API object using Swagger 2.0 or OpenApi 3.x?
body: <p>I am documenting a REST API (developed in Go) using Swagger 2.0 and one of the structures used by an API Response includes several fields that are declared to be of type "Json.RawMessage" in Go. I can't find any appropriate "data type" in the Swagger specification that would cover this. The closest that I could imagine would be a string in "byte" format. But that isn't even close. Any ideas would be of great help.</p>
