Section 12.1 / 12.2 says:

 Section 12.1:   Upon the receipt of a valid Reply message, for each IA_PD the   requesting router assigns a subnet from each of the delegated   prefixes to each of the links to which the associated interfaces are   attached, with the following exception: the requesting router MUST   NOT assign any delegated prefixes or subnets from the delegated   prefix(es) to the link through which it received the DHCP message   from the delegating router.

It should say:

 Section 12.1:   Upon the receipt of a valid Reply message, for each IA_PD the   requesting router assigns a subnet from each of the delegated   prefixes to each of the links to which the associated interfaces are   attached.New last paragraph of 12.2:  When the DR delegates prefixes to a Requesting Router, the  Requesting Router has sole authority for assignment of those  prefixes, and the Delegating Router MUST NOT assign any prefixes  from that delegated prefix to any of its own links.

Notes:

This change clarifies that the authority over the address space is delegated to the RR (Requesting Router). Moving the use restriction for the address space from the DR (Delegating Router) to the RR (Requesting Router).

Section 11.2 says:

If the delegating router will not assign any prefixes to any IA_PDsin a subsequent Request from the requesting router, the delegatingrouter MUST send an Advertise message to the requesting router thatincludes the IA_PD with no prefixes in the IA_PD and a Status Codeoption in the IA_PD containing status code NoPrefixAvail and a statusmessage for the user, a Server Identifier option with the delegatingrouter's DUID and a Client Identifier option with the requestingrouter's DUID.

It should say:

If the delegating router will not assign any prefixes to an IA_PDin a subsequent Request from the requesting router, the delegatingrouter MUST send an Advertise message to the requesting router thatincludes the IA_PD with no prefixes in the IA_PD and a Status Codeoption in the IA_PD containing status code NoPrefixAvail and a statusmessage for the user, a Server Identifier option with the delegatingrouter's DUID and a Client Identifier option with the requestingrouter's DUID. The server SHOULD include other stateful IA options(like IA_NA) and other configuration options in the Advertise message.

Notes:

Edited by Ralph Droms on 2010-08-20 to correct reference to IA_NA (was IA_PD) in last line.

Section 9 says:

   If a requesting router receives an IA_PD with T1 greater than T2, and   both T1 and T2 are greater than 0, the client discards the IA_PD   option and processes the remainder of the message as though the   delegating router had not included the IA_PD option.

It should say:

   If a requesting router receives an IA_PD with T1 greater than T2, and   both T1 and T2 are greater than 0, the requesting router discards the IA_PD   option and processes the remainder of the message as though the   delegating router had not included the IA_PD option.

Section 9 says:

   If a delegating router receives an IA_PD with T1 greater than T2, and   both T1 and T2 are greater than 0, the delegating router ignores the   invalid values of T1 and T2 and processes the IA_PD as though the   delegating router had set T1 and T2 to 0.

Section 14 says:

If a delegating router communicates with a requesting router througha relay agent, the delegating router may need a protocol or otherout-of-band communication to add routing information for delegatedprefixes into the provider edge router.

It should say:

If a delegating router communicates with a requesting router througha relay agent, the delegating router may need a protocol or otherout-of-band communication to configure routing information for delegatedprefixes on any router through which the requesting router may forwardtraffic.
