Hello Tatuya,

Thank you for the careful review.  Follow-up below:

This is correct.  I will fashion some language as suggested.  I think it 
is appropriate to allow ULAs, but multicast and unspecified addresses 
seem clearly inappropriate, and I am i favor of disallowing link-local 
addresses.

I don't quite know what to do about this.  I actually just copied this 
language from RFC 3315.  I think that the citation is also wrong in RFC 
3315, for the same reason as given here.  I could simply delete the 
reference to RFC 2464.

Fixed.  I also checked for other similar instances and did not find any.
