Just an update to add the following change to the AD review list:

> In the definition of Picture ID, in section 4.2, in the phrase "if the field 
> transitions from 15 bits to 7 bits, it is truncated (i.e., the value after 
> 0x1bbe is 0xbf)” the value “0xbf” should be replaced by “0x3f”.  (0xbf is not 
> a 7-bit value.)

Thank you.
