Does OpenRPC supports something like "discriminator" for oneOf and anyOf?

[svetlyak40wt]

OpenAPI supports it and this feature is useful when writing code-generated API wrappers.

Here is how it looks like in the OpenAPI spec:

components:
  responses:
    sampleObjectResponse:
      content:
        application/json:
          schema:
            oneOf:
              - $ref: '#/components/schemas/Object1'
              - $ref: '#/components/schemas/Object2'
              - $ref: 'sysObject.json#/sysObject'
            discriminator:
              propertyName: objectType
              mapping:
                obj1: '#/components/schemas/Object1'
                obj2: '#/components/schemas/Object2'
                system: 'sysObject.json#/sysObject'

Example was taken from here.
