Summary: This document is ready for publication as a Proposed Standard RFC
                   There are two issues that I think should be addressed
                   before publication

Major issues: N/A

Minor issues:
   This depends upon CDNs which have not been upgraded not stripping this
   header.  While I can believe that is a reasonable assumption, it seems that
   a paragraph explaining that it is the case, and if possible what experience
   leads us to think it is the case, would be helpful.

   This document says that it is to protect against attackers causing loops. 
   If the attacker is an external customer, the advice in the security
   considerations section makes sense.  The other apparent attack would be an
   attacker in the network who strips the information each time it comes past.
    I believe the reason this is only an apparent attack is that such an
   attacker could almost as easily simply generate additional messages instead
   of producing a loop.  If I have inferred this correctly, it seems useful to
   state it.

Nits/editorial comments:  N/A
