Section 4.2 says:

      2 The use of the symbols in 2/2, 2/7, 2/12, 5/14, /6/0, and 7/14
   as diacritical marks is described in Appendix A, A5.2
      3 These characters should not be used in international interchange
   without determining that there is agreement between sender and
   recipient.  (See Appendix B4.)

It should say:

     2 The use of the symbols in 2/2, 2/7, 2/12, 5/14, /6/0, and 7/14
   as diacritical marks is described in Appendix A, A5.2, of X3.4-1968.
      3 These characters should not be used in international interchange
   without determining that there is agreement between sender and
   recipient.  (See Appendix B4 of X3.4-1968.)

Notes:

The appendixes are in the original standard, not the RFC.

In the abstract, it says "X3, 4-" rather than "X3.4-" which is surely an OCR or transcription error.
