Integrating with existing JSON schemas

[jzillmann]

Hey there,

following problem...
I have existing (dynamic) JSON schema's coming from the backend. Sometimes I want to use them directly, sometimes enrich them with frontend only types created by typebox.
So something like that

const S = Type.Object(connector.configurationSchema)
const T = Type.Object({
    connectionName: Type.String(),
})

const CompleteSchema = Type.Intersect([S, T])

While that works great with avj, I can't use some of the typebox helpers.
E.g. Value.Create(CompleteSchema) fails with

Error: Unknown type

    at Object.Create3 (@sinclair_typebox_value.js?v=9bc4dcdb:3263:18)

I guess it is because the json-schema definitions from the backend don't have type symbols (like Symbol(TypeBox.Kind)).
Is there some utility method to convert a 'external' schema definition into a 'typebox' one ?
