Just two questions after a quick reading...

Is there any particular reason for including Framed-Pool instead of 
Framed-IPv6-Pool?
What about Framed-IPv6-Prefix?
Generally, what's the criteria for choosing which attributes to include?

Your draft states:

>     The option-data of OPTION_RADIUS is one or a list of RADIUS
>     attributes received in the Access-Accept message from the RADIUS
>     server.  As the same method in [RFC4014  <http://tools.ietf.org/html/rfc4014>], only the attributes listed
>     in the table below may be included in the OPTION_RADIUS.

RFC 4014 states:

>     To avoid dependencies between the address allocation and other state
>     information between the RADIUS server and the DHCP server, the DHCP
>     relay agent SHOULD include only the attributes in the table below in
>     an instance of the RADIUS Attributes suboption.  The table, based on
>     the analysis inRFC 3580  <http://tools.ietf.org/html/rfc3580>  [8  <http://tools.ietf.org/html/rfc4014#ref-8>], lists attributes that MAY be included:


I'm trying to understand if RFC 4014 refers to DHCPv4 only and if your 
draft refers to DHCPv6 only, and if yes, why a DHCPv4 server should know 
about an IPv6 attribute and vice versa.
