Folks,

Given Dino's response in 
http://www.ietf.org/mail-archive/web/lisp/current/msg05945.html, shouldn't we 
remove the entire bullet item? As Dino says, "An ITR or PITR will encapsulate 
to a PETR, not when a cache miss happens but when the mapping system returns a 
"forward-native" action in a Null Map-Reply (one with no locator-set)."
