Hi

I have some question:
 
In section 3, the second paragraph:
"The DHCP server MAY include this option in a Reply message sent to a
   client that includes assigned addresses and/or prefixes.  If the DHCP
   server does include this option in a Reply message, it MUST include
   it in the option area of the Relay-reply message sent to the relay
   agent intended as the recipient of the option."

1) "The DHCP server MAY include this option in a Reply message ...." .
------ Why?  To minimize the DHCP packet size(it's the reason I guess), or
other reasons? 
2) "If the DHCP server does inclue this option in a Reply messge, it MUST
include...". ---------- So, there is more than one RAAN options in a
Relay-reply message. Is the RAAN option included in a Reply message useful?
Or it should be "does not" ?
3) If DHCP client receives a reply message containing a RAAN option, how
does the DHCP client handle the RAAN option? ignore?
4) If DHCP server receives a relay-forw message requesting RAAN, when it
answers, should it insert the RAAN option into the reply message or the
relay-reply message?
 
Two editing nits 
1)in Section 5:
 The last sentence ".......by setting a shorter valid-lifetime in the this
option",  should change "in the this option" to "in the corresponding
option"?
2)In Section 3:
The first sentence "The RAANn option carries information about.....",
should change "RAANn" to "RAAN"?
