 Thus, a token SHOULD have an expiration time, which could be either an explicit
 expiration time or an issued timestamp that can be used to dynamically calculate
 the expiration time.  A server can store the expiration time or include it in an
 encrypted form in the token.
+A token issued with NEW_TOKEN MUST NOT include information that would allow
+values to be linked by an on-path observer to the connection on which it was

Note that we have inconsistent terminology: and "off-path" attack can still read packets in the threat model, but here an "on-path" observer can see packets presumably as opposed to "off-path".
