-If the `_X_AMZN_TRACE_ID` environment variable is set, instrumentation SHOULD try to parse an
-OpenTelemetry `Context` out of it using the [AWS X-Ray Propagator](https://github.com/open-telemetry/opentelemetry-specification/tree/v1.22.0/specification/context/api-propagators.md). If the
-resulting `Context` is [valid](https://github.com/open-telemetry/opentelemetry-specification/tree/v1.22.0/specification/trace/api.md#isvalid) then a [Span Link][] SHOULD be added to the new Span's
-[start options](https://github.com/open-telemetry/opentelemetry-specification/tree/v1.22.0/specification/trace/api.md#specifying-links) with an associated attribute of `source=x-ray-env` to
-indicate the source of the linked span.
-Instrumentation MUST check if the context is valid before using it because the `_X_AMZN_TRACE_ID` environment variable can
-contain an incomplete trace context which indicates X-Ray isn’t enabled. The environment variable will be set and the
-`Context` will be valid and sampled only if AWS X-Ray has been enabled for the Lambda function. A user can
-disable AWS X-Ray for the function if the X-Ray Span Link is not desired.
+If the `_X_AMZN_TRACE_ID` environment variable is set, instrumentation MUST ensure that the value from that
+environment variable is included in the `Carrier` used to extract a parent `Context` with the `Field` name
+"X-Amzn-Trace-Id".
 
-**Note**: When instrumenting a Java AWS Lambda, instrumentation SHOULD first try to parse an OpenTelemetry `Context` out of the system property `com.amazonaws.xray.traceHeader` using the [AWS X-Ray Propagator](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/context/api-propagators.md) before checking and attempting to parse the environment variable above.
