reword:

   For those IPv6 nodes that implement DHCP, those nodes MUST use DHCP
   upon the receipt of a Router Advertisement with the 'M' flag set (see
   section 5.5.3 of RFC2462).  In addition, in the absence of a router,
   IPv6 Nodes that implement DHCP MUST attempt to use DHCP.

to:

   Nodes that implement DHCP MUST use DHCP upon the receipt of a 
   Router Advertisement with the 'M' flag set (see section 5.5.3 of 
   RFC2462).  In addition, in the absence of a router,
   IPv6 Nodes that implement DHCP MUST attempt to use DHCP.  In this 
   context, 'use DHCP' means trying to obtain both address(es) and 
   other configuration information through DHCP.

reword:

   For those IPv6 Nodes (acting as hosts) that implement DHCP, those
   nodes MUST use DHCP upon the receipt of a Router Advertisement with
   the 'O' flag set (see section 5.5.3 of RFC2462).  In addition, in the
   absence of a router, hosts that implement DHCP MUST attempt to use
   DHCP. For IPv6 Nodes that do not implement DHCP, the 'O' flag of a
   Router Advertisement can be ignored.  Furthermore, in the absence of
   a router, these types of node are not required to initiate DHCP.

to:

   IPv6 Nodes (acting as hosts) that implement DHCP, MUST use DHCP upon 
   the receipt of a Router Advertisement with the 'O' flag set (see 
   section 5.5.3 of RFC2462).  In addition, in the
   absence of a router, hosts that implement DHCP MUST attempt to use
   DHCP. In this context, 'use DHCP' means trying to obtain only other 
   configuration information through DHCP, not address(es).

   IPv6 Nodes that do not implement DHCP can ignore the 'O' flag 
   of a Router Advertisement.  Furthermore, in the absence of
   a router, these types of node are not required to initiate DHCP.

(these are not only editorial issues IMHO, especially the latter one, 
if someone is envisioning that in absence of a router, DHCP should try 
to get an address as well, from the context of other config 
information)
