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

In this document, I see:

   IPv6 nodes SHOULD implement Path MTU Discovery in order to discover
   and take advantage of paths with PMTU greater than the IPv6 minimum
   link MTU [I-D.ietf-6man-rfc2460bis].  A minimal IPv6 implementation
   (e.g., in a boot ROM) may choose to omit implementation of Path MTU
   Discovery.

In draft-ietf-6man-rfc2460bis-09:
   It is strongly recommended that IPv6 nodes implement Path MTU
   Discovery [RFC1981], in order to discover and take advantage of path
   MTUs greater than 1280 octets.  However, a minimal IPv6
   implementation (e.g., in a boot ROM) may simply restrict itself to
   sending packets no larger than 1280 octets, and omit implementation
   of Path MTU Discovery.

So a SHOULD in one document versus "strongly recommended" in the other.

We should reconcile the two texts.
Note: may and may are consistent.


ICMPv6 PTB => ICMPv6 Packet to Big (PTB)
