Add guidelines on how CBOR messages are mapped onto streams #334
Description
Provisionally, each CBOR message gets mapped onto one QUIC stream. This allows the message to be delivered to the agent as soon as it is fully received. However, this is not made explicit in the spec.
In QUIC, there are per-connection limits on the number of simultaneous streams. We may need to group multiple messages into a single stream if the limits are too low. Need to research what the practical limits are in current implementation (i.e. QUICHE).
