Section 4.3 says:
L-13: If the delegated prefix changes, i.e., the current prefix is
replaced with a new prefix without any overlapping time
period, then the IPv6 CE router MUST immediately advertise the
old prefix with a Preferred Lifetime of zero and a Valid
Lifetime of the lower of the current Valid Lifetime and 2
hours (which must be decremented in real time) in a Router
Advertisement message as described in Section 5.5.3, (e) of
[RFC4862].
It should say:
L-13: If the delegated prefix changes, i.e., the current prefix is
replaced with a new prefix without any overlapping time
period, then the IPv6 CE router MUST immediately advertise the
old prefix with a Preferred Lifetime of zero and a Valid
Lifetime of either a) zero, or b) the lower of the current
Valid Lifetime and 2 hours (which must be decremented in real
time), in a Router Advertisement message as described in
Section 5.5.3, (e) of [RFC4862].
Notes:
The original text in L-13 prohibits implementers from transmitting Valid Lifetime = 0 whenever a prefix needs to be invalidated. It should not, because transmitting VL=0 is easier to implement than sending "the lower of the current Valid Lifetime and 2 hours (which must be decremented in real time)".
Transmitting Valid Lifetime = 0 has the exact same effect on a host as the procedure described in the original text, i.e., it will the host to lower (but never raise) the remaining valid lifetime to 7200 seconds.

Section 4.2 says:
WPD-3: The IPv6 CE router MUST be prepared to accept a delegated
prefix size different from what is given in the hint. If the
delegated prefix is too small to address all of its
interfaces, the IPv6 CE router SHOULD log a system management
error.
It should say:
WPD-3: The IPv6 CE router MUST be prepared to accept a delegated
prefix size different from what is given in the hint. If the
delegated prefix is too small to address all of its
interfaces or delegated prefix size is greater than /64, the
IPv6 CE router SHOULD log a system management
error.
Notes:
Stateless Address Auto configuration uses 64 bit long EUI-64. If Delegated prefix size obtained on the wan side is greater than /64. This Prefix cannot be used on Lan side nodes to create SLAAC address using EUI-64
--VERIFIER NOTES--
RFC 6204 is about to be obsoleted by draft-ietf-v6ops-6204bis, which entered WG last call this weekend. So, fixing 6204 won't help much.
Please post a message to the V6OPS mailing list making the point that you make in the errata. If the WG agrees, the change will be made in the bis document.
