A few comments; I haven't looked too deep into DHCPv6 to be able to 
comment on those parts, but there are some definite need for revisal in 
the doc..:

2. Requirements

   The key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
   [...]

==> I'd put these under Introduction or Terminology sections, no use 
having a separate section with a questionable title.

   option-length: Length of the 'options' field in octets; must be a
      multiple of 16

==> 'options' field has not been defined.  Is it the whole option or just
the length of DNS-server address options (I assume so)?  If the former,
there must be 32 bits of zero padding.  Is it ok that the options aren't 
64-bit aligned?

   The list of domain names in the 'searchstring' MUST be encoded as
   specified in section "Representation and use of domain names" of the
   DHCPv6 specification [4].

==> I didn't bother to check, but I guess this document also defines how 
to pad the names to get some desired level of alignment?

6. Appearance of these options

   The Domain Name Server option MUST appear only in the following
   messages: Solicit, Advertise, Request, Confirm, Renew, Rebind, 
   Information-Request, Reply.

   The Domain Search List option MUST appear only in the following
   messages: Solicit, Advertise, Request, Confirm, Renew, Rebind, 
   Information-Request, Reply.

==> I would reword these differently, like:

 The Domain Name Server option MUST NOT appear in other than the following 
messages: ....

==> is it ok to server to give only one of these options but not the 
other?

References

==> split the references
