+Jaeger Tracer supports an additional [span reference][] type call `Self`, which was proposed
+to the OpenTracing Specification (https://github.com/opentracing/specification/issues/81)
+but not yet accepted. This allows the caller to provide an already created `SpanContext`
+when starting a new span. The `Self` reference bypasses trace and span id generation,
+as well as sampling decisions (i.e. the sampling bit in the `SpanContext.flags` must be
+set appropriately by the caller).
 
+The `Self` reference supports the following use cases:
+  * the ability to provide externally generated trace and span IDs
+  * appending data to the same span from different processes, such as loading and continuing spans/traces from offline (ie log-based) storage
