2.6. Appendices. The appendices for an IS-ICD are the same as for a regular ICD.

For reference or comparison, below is what the JCIDS Manual says for the ICD 2021 itself:

2.6. Appendices. Only the following appendices are allowed in the document:

2.6.1. Since ICDs are Service, solution and cost agnostic and about MOEs, not about a materiel solution, Appendix E and Appendix F are optional, unless there is specifics relevant to the recommendation and domain in which the ICD is for.

2.6.4. Appendix C. Glossary.

2.6.4.1. Add statement: "Unless otherwise stated, the terms and definitions contained in this glossary are for the purposes of this document only."

2.6.4.2. As the Sponsors develop the document glossary, they may leverage applicable definitions from the DoDAF AV-2. These do not have to be identical as some terms will apply only to the document or the DoDAF architecture; however, terms that apply to both must be consistent. Definitions should first reflect use terminology from in the DOD Dictionary, if not then subsequently the Terminology Repository, both found at the DOD Terminology Webpage on the CAC-enabled Joint Electronic Library Plus "+" website - https://jdeis.js.mil/jdeis/index.jsp. Any deviation from existing DOD Dictionary terms should be explained in the glossary. Term source must be identified following the definition.

2.6.4.3 As the Sponsor develops the document glossary, they may leverage applicable definitions from the DoDAF AV-2. These do not have to be identical as some terms will apply only to the document or the DoDAF architecture; however, terms that apply to both must be consistent
