COMMENT:
----------------------------------------------------------------------

Let me append my COMMENT. 
Since the companion MIB document didn't compile
(https://datatracker.ietf.org/doc/draft-ietf-softwire-mesh-mib/ballot/#benoit-claise)
, I made some extra test with this MIB module.

Thanks for addressing Dave Thaler's recommendations.

The only point that looks under specified to me is:
      dsliteNATBindMappingExtAddressType OBJECT-TYPE
          SYNTAX InetAddressType
          MAX-ACCESS not-accessible
          STATUS current
          DESCRIPTION
            "Address type for the mapping's external address.
             A value other than IPv4(1) would be unexpected."
          ::= { dsliteNATBindEntry 4 }


    dsliteNATBindMappingIntAddressType OBJECT-TYPE
          SYNTAX InetAddressType
          MAX-ACCESS read-only
          STATUS current
          DESCRIPTION
             "Address type of the mapping's internal address.
              A value other than ipv4z(3) would be unexpected."
          ::= { dsliteNATBindEntry 8 }

What does it mean: "other value would be unexpected"?
Is this allowed or not?

You can access any intermediately created files, the processing report
(which might be empty if no errors or warnings have been found), and
output files (in case of a conversion request) for reading and download
from a temporary server directory for approx. 24 hours.

While processing your request the following errors and/or warnings have
been found:

mibs/NATV2-MIB:368: warning: identifier `natv2SubscriberIndex' differs
from `Natv2SubscriberIndex' only in case
mibs/NATV2-MIB:109: info: previous definition of `Natv2SubscriberIndex'

mibs/DSLite-MIB:712: [5] {notification-not-reversible} warning:

imported from module `SNMPv2-SMI' is never used
mibs/DSLite-MIB:13: [5] {import-unused} warning: identifier
`DisplayString' imported from module `SNMPv2-TC' is never used

You could take care of the last 3 warnings.
Also, I inquired about the "notification X  is not reverse mappable" to
the MIB-doctors.
Here is Jürgen Schönwälder's answer:
SNMPv1 identifies notifications in a different way that SNMPv2c/SNMPv3
does and SMIv2 notification definitions are reverse mappable if they
are registered OID.0.X and smilint generates this warning if they are
not. This is the reason why the generally suggestion MIB OID layout
has a notifications branch registered with the subidentifier 0.

The MIB module in question has

dsliteNotifications  OBJECT IDENTIFIER
         ::=  { dsliteMIB 0 }

dsliteTraps  OBJECT IDENTIFIER
            ::=  { dsliteNotifications 1  }

and the notification registered below dsliteTraps. I do not think this
serves any purpose - if authors would simply follow RFC 4181 appendix
D the problem would not show up. (And in general, we talk about
notifications not traps in SMIv2.)

See also section 4.7 of RFC 4181.

Authors, please improve your MIB module to be compliant with RFC 4181.

Regards, Benoit
