Section 4.3.1 says:

If the F bit is set to zero
      (see below), then the NT field has no meaning and MUST be ignored
      by the receiver. 

It should say:

If the F bit is set to one
      (see below), then the NT field has no meaning and MUST be ignored
      by the receiver. 

Notes:

Later it says, when this F bit is set to 1, the NAI value is absent, so the NT field has no meaning.
F: When this bit is set to 1, the NAI value in the subobject
body is absent. The F bit MUST be set to 1 if NT=0;
otherwise, it MUST be set to zero. The S and F bits MUST NOT
both be set to 1.
