Summary: Almost Ready

Thank you for addressing my previous comments.


Major Concerns:

Section 3.2.4: Since none of the Key Types is mandatory-to-implement, it
is possible that two implementations of this specification will not
interoperate.  I realize that the Key Type have very different security
implications.  Also, mandatory-to-implement does not make that Key Type
mandatory-to-use. Policy has a role too.

Section 8: The IANA registry indicates that Feature Number 10 was given
a temporary assignment.  I expected to see a similar temporary assignment
for Option Type 46.  This document seems to depend on that value being
assigned by IANA.


Minor Concerns:

None.


Nits:

Section 3.11.2: Please add white space between the adjacent paragraphs.
