 ### Tracking sampling policy
 To better understand _which_ sampling policy made the decision to include a trace, you can enable tracking the policy responsible for sampling a trace via the `processor.tailsamplingprocessor.recordpolicy` feature gate.
 
-When this feature gate is set, this will add additional attributes on each sampled span scope:
