The Cabin Safety Subject Index describes itself as: “The Cabin Safety Subject Index (CSSI) is a reference guide to Federal Regulations, FAA Orders, Advisory Circulars, Information for Operators (InFO), Safety Alerts for Operators (SAFO), legal interpretations, and other FAA related content related to cabin safety.” Therefore, the contents are not all “LAW”, as many have tried to claim in the comments. There is also no penalty listed, only requirements for airline staff and operators.
