Section B.3 says:

   | 064    | 00 00 00 03  | isutccnt         | 1                      |
   | 068    | 00 00 00 03  | isstdcnt         | 1                      |
   | 072    | 00 00 00 00  | isleapcnt        | 0                      |
   | 076    | 00 00 00 03  | timecnt          | 1                      |
   | 080    | 00 00 00 03  | typecnt          | 1                      |
   | 084    | 00 00 00 08  | charcnt          | 4                      |

It should say:

   | 064    | 00 00 00 01  | isutccnt         | 1                      |
   | 068    | 00 00 00 01  | isstdcnt         | 1                      |
   | 072    | 00 00 00 00  | isleapcnt        | 0                      |
   | 076    | 00 00 00 01  | timecnt          | 1                      |
   | 080    | 00 00 00 01  | typecnt          | 1                      |
   | 084    | 00 00 00 04  | charcnt          | 4                      |

Notes:

The numbers 1 and 4 are incorrectly encoded as big-endian 32-bit integer values. I'm guessing that the example originally used more data and was then trimmed down (from 3 to 1 for isutccnt, isstdcnt, timecnt, and typecnt, and from 8 to 4 for charcnt) but the integer encodings were never updated.

Verifier's notes: The errata is correct, but incomplete, as there are several errors in these tables. An update to the document implementing the fix is being worked on.
