Section 8.2, p.69 says:

 tcp_opt_generic
 {
   UNCOMPRESSED {
     type                                    [ 8 ];
     length_msb =:= uncompressed_value(1, 0) [ 1 ];
     length_lsb                              [ 7 ];
|    contents                           [ length_len.UVALUE*8-16 ];
   }
                                                 ^^^

It should say:

 tcp_opt_generic
 {
   UNCOMPRESSED {
     type                                    [ 8 ];
     length_msb =:= uncompressed_value(1, 0) [ 1 ];
     length_lsb                              [ 7 ];
|    contents                           [ length_lsb.UVALUE*8-16 ];
   }
                                                 ^^^

Notes:

'length_len' has never been introduced.
This must be a confusing typo, invalidating the formal specification.

Tis same correction needs to be applied once more, near the bottom
of page 69.
