2.6.5. Appendix D. (Optional) Classified Appendix. A classified appendix may be used in cases where only a small subset of the document needs to be protected at a higher classification level. If the document is not useful without this appendix, the document is to be classified at a higher level. A classified appendix's content will count toward the document body page limits and will be indexed to align with the baseline document sections. Except where the existence of classified content cannot be acknowledged, each section of the baseline document augmented by the classified appendix will refer the reader to the classified appendix. If used, the appendix shall be provided to the Joint Staff Gatekeeper or J-8/SAPCOORD IAW the classification of the appendix.
