Summary:

I have three small points for the group to consider:

1) In editing for this bis document, one bit of text was lost. 
RFC4291 said this in its section 2.4.5:
"Global Unicast addresses that start with
 binary 000 have no such constraint on the size or structure of the
 interface ID field."
Without it, the various places remaining the the document that say
things like "except those that start with the binary value 0000"
such as that appearing in section 2.4 of _this_ document leave
the reason behind the exception a mystery.

2) At the point in the text where the modified EUI-64 format interface
identifier text was moved to the appendix, this document notes that 
these derived interface identifiers are no longer recommended (end of
2.4.1). Consider repeating that at the first line of the new Appendix A.

3) Appendix B looks like something groups normally ask the RFC Editor to
delete. If that was your intent, please add instructions to the RFC Editor
so they don't have to ask. If you planned to leave it, a summary of the
changes rather than a chronolog of what draft version changes were made
in would be much more useful to future readers. (Such a summary would
be welcome in any case.)
