I understand your comment. However, the issues you are raising (as well as others) related to 6to4 are already in the 6to4 security RFC (RFC3964), which is already referenced in the 6to4 paragraph. Therefore, I would suggest not to add any additional text in order to not repeat what is already throughly discussed in RFC3964.
I think readers would be well-served by a convenient, local  
reference though. If it is left to the reader to translate RFC 3330  
into hex, chances are good that it won't happen.

routing policy instructions.

How about adding some additional text to section 2.7, such as:

6to4 prefixes are constructed by embedding an IPv4 address into an IPv6 prefix according to [RFC3056]. Where the IPv4 address used to construct such a prefix is not globally-unique (or is otherwise reserved), the resulting 6to4 prefix is unlikely to be useful.
The following is a summary of 6to4 prefixes constructed using  
special-use IPv4 addresses, as documented in [RFC3330]. IPv4  
prefixes which appear in [RFC3330] but which are known to have  
legimitate use on the public Internet at the time of writing are  
not included. Operators are advised to derive a policy for  
treatment of these 6to4 prefixes which is analogous to their policy  
for the corresponding IPv4 addresses.
  IPv4 Prefix     Description                       6to4 Prefix

  0.0.0.0/8       "this network" [RFC1700]          2002::/24
  10.0.0.0/8      private networks [RFC1918]        2002:a00::/24

  169.254.0.0/16  "link local"                      2002:a9fe::/32
  172.16.0.0/12   private networks [RFC1918]        2002:ac10::/28
  192.0.2.0/24    "test net"                        2002:c000:200::/40

  (etc, etc)
