Section 8.1 says:
On page 46 start from line 7: "When max-dpb is signaled, the receiver MUST be able to decode NAL unit streams that conform to the signaled highest level, with the exception that the MaxDpbMbs value in Table A-1 of [1] for the signaled highest level is replaced with the value of max-dpb * 3 / 8. Consequently, a receiver that signals max-dpb ^^^^^ MUST be capable of storing the following number of decoded frames, complementary field pairs, and non-paired fields in its decoded picture buffer: Min(max-dpb * 3 / 8 / ( PicWidthInMbs * FrameHeightInMbs), ^^^^^ 16)"
It should say:

Section 8.1 says:
profile-level-id: A base16 [7] (hexadecimal) representation of the following three bytes in the sequence parameter
It should say:
profile-level-id: A base16 [7] (hexadecimal) representation of the following six bytes in the sequence parameter
Notes:
profile-level-id is composed of three 2-byte length fields.
--VERIFIER NOTES--
The original text is correct; 3 bytes in the binary representation become 6 text characters in base16.

Section 8.2.2 says:
To simplify the handling and matching of these configurations, the same RTP payload type number used in the offer SHOULD also be used in the answer, as specified in [8] [8] points to RFC 3264 "An Offer/Answer Model with the Session Description Protocol (SDP)"
Notes:
The above statement is wrong. RFC 3264 does not mandate the same payload
type in both the offer and the answer. In fact, RFC 3264 section 5.1 states:
For sendonly RTP streams, the payload type
numbers indicate the value of the payload type field in RTP packets
the offerer is planning to send for that codec. For sendrecv RTP
streams, the payload type numbers indicate the value of the payload
type field the offerer expects to receive, and would prefer to send.
However, for sendonly and sendrecv streams, the answer might indicate
different payload type numbers for the same codecs, in which case,
the offerer MUST send with the payload type numbers from the answer.
--VERIFIER NOTES--
Rejected based on discussion on avtcore and payload lists. (3264 does in fact include the SHOULD).
