-
 The OpenTelemetry Propagator for AWS X-Ray provides HTTP header propagation for systems that are using AWS `X-Amzn-Trace-Id` format.
 This propagator translates the OpenTelemetry SpanContext into the equivalent AWS header format, for use with the OpenTelemetry JS SDK.
 `TraceState` is currently not propagated.
 
-Compatible with OpenTelemetry JS API and SDK `1.0+`.
