Section 8.2, p.67 says:

   COMPRESSED sack2_list_item {
     discriminator =:= '00000010';
     block_1       =:= sack_block(ack_value);
     block_2       =:= sack_block(block_1_end.UVALUE);
     ENFORCE(length.UVALUE == 18);
   }

It should say:

   COMPRESSED sack2_list_item {
     discriminator =:= '00000010';
     block_1       =:= sack_block(ack_value);
|    block_2       =:= sack_block(block_1.UVALUE && 0xFFFFFFFF);
     ENFORCE(length.UVALUE == 18);
   }

Notes:

ROHC-FN is intended to introduce precision.
Therefore, no ad-hoc variable names should be introduced,
independent of how mnemonic their names might be.

I hope that the NEW text substituted above indeed is what had been
intended.

Similar corrections need to be applied on page 68 (10 instances)
and on top of page 69 (one instance).
