    abstract =  {This document discusses how to inform Service Functions about service- and subscriber-related information for the sake of policy enforcement and appropriate SFC-inferred forwarding. Once the information is consumed by SFC-aware elements of an SFC-enabled domain, it is stripped from packets when they leave the SFC-enabled domain. Thus privacy-sensitive information is not leaked outside the domain.},
