JSON-RPC 1.0 support for clients

[ivan770]

Is it possible for JSON-RPC clients to use 1.0 scheme instead of 2.0? Looks like currently successful and error responses are separate entities, and there is no configuration for Compatibility (like in IoHandler).

No, it's not supported currently.
The RequestBuilder controls the jsonrpc version and it's not possible to configure it to use jsonrpc 1.0.
