How to use IDL

IDL dependencies can be straightforwardly specified in OAS specifications using IDL4OAS, an OAS extension. You just need to include the keyword x-dependencies at the operation level, and include the list of dependencies as an array. Take a look at this simple example:

paths:
  /example/route:
    get:
      operationId: exampleOperation
      parameters:
        - in: query
          type: boolean
          required: false
          name: p1
        - in: query
          type: integer
          required: false
          name: p2
        - in: query
          type: string
          required: false
          name: p3
      x-dependencies:
        - Or(p1, p2, p3);
        - IF p1==true THEN p2;
