Ok - sorry for spamming but the same ETX inconsistency is here
in this version also (8 vs 16 bits).

Early in the section it is specified:
"Each ETX sub-object has a fixed length of 8 bits"

But just below there is a figure and a text explaining
that it is 16 bits:

  0                   1
  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|              ETX              |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

  Figure 13: ETX sub-object format

ETX: 16 bits. The ETX * 128 is encoded using 16 bits in unsigned
integer format, rounded off to the nearest whole number.
