Short version

Context propagation protocol

application SDK MUST propagate trace parent part of the context (version, traceId, parentId and traceFlags) in the message in Diagnostic-Id application property following W3C trace-context format for traceparent encoding.

Also, propagate W3C trace context using W3C Trace Context Propagator from OpenTelemetry. It should populate traceparent and tracestate application properties. traceparent must match Diagnostic-Id value.

When extracting the context, first get W3C trace-context and then (if missing) read Diagnostic-Id.
