PHP negotiation

Hi all,
     The following paragraph is from Section 3.16. (Penultimate Hop Popping) of
RFC3031.


   "Initial label distribution protocol negotiations MUST allow each LSR
   to determine whether its neighboring LSRS are capable of popping the
   label stack.  A LSR MUST NOT request a label distribution peer to pop
   the label stack unless it is capable of doing so."

     However, I can not find any mechanism in LDP/CR-LDP or RSVP-TE  to
accomplish this PHP negotiation.

     Am I missing something here?
