The Problem
STD action in RTG area requires implementations
Certain code-point ranges use “STD action” policy
Implementers can’t get codes from IANA, pick next available (X)---BAD!
Risk of collisions when X is allocated by IANA or another early implementation uses it

Seen this problem with RSVP FLOWSPEC and SENDER_TSPEC C-Types
IDR: new BGP spec uses STD action as the policy
