   This document describes the mechanism to associate network resource
   attributes to Segment Routing Identifiers (SIDs).  Such SIDs are
   referred to as resource-aware SIDs in this document.  The resource-
   aware SIDs retain their original forwarding semantics, but with the
   additional semantics to identify the set of network resources
   available for the packet processing action.  The resource-aware SIDs
   can therefore be used to build SR paths or virtual networks with a
   set of reserved network resources.  The proposed mechanism is
   applicable to both segment routing with MPLS data plane (SR-MPLS) and
   segment routing with IPv6 data plane (SRv6).
