Authors,


In draft-jags-mpls-ps-mna-hdr you have:

10.3.  Top Header Types Registry

   This document requests that IANA create a new registry with the name
   "Top Header Types".  The registration procedure for this registry is
   "IETF Review".  The fields are "Type" (integer), "Description"
   (string), and "Reference" (string).  Type is an integer 0-65535.

   The initial assignments for this registry are:

           +=============+=====================+===============+
           | Type        |     Description     | Reference     |
           +=============+=====================+===============+
           | 0           | Reserved            | This document |
           +-------------+---------------------+---------------+
           | 1           | POST-STACK-MNA-TYPE | This document |
           +-------------+---------------------+---------------+
           | 2-65520     | IETF Review         | This document |
           +-------------+---------------------+---------------+
           | 65521-65524 | Experimental Use    | This document |
           +-------------+---------------------+---------------+
           | 65525-65535 | Private Use         | This document |
           +-------------+---------------------+---------------+

                     Table 3: Top Header Types Registry

A few comments:

- The of the registry is too broad, I would suggest "MNA Post-Stack Feader
Types "Registry".

- Rserved for the code point zero  should be "Rserved, not to be assigned"
- The "IETF Review" for the unassigned code point is mislpaced, it should
  be "Unassigned", I the Registration Procedure goes on top of the
   registry.
