Summary	0009060: Discussion: How could open telemetry/W3C trace context be added to OPC UA request headers?
Description	Open telemetry is an incubation project but already widely used in the IT world for distributed logging, tracing etc. https://opentelemetry.io/ is a CNCF incubation project. From W3C there is a standard https://www.w3.org/TR/trace-context/ which defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. This format is also supported by open telemetry and already supported by many libraries. The discussion were to find out how that standard could be mapped to a OPC UA request header, or if there are better ways to do this. Best case issue a recommendation / appendix.
