Adopt the NATO STANAG 4774 (Confidentiality Metadata Label) XML schema as the canonical confidentiality labelling format for classified and protectively marked information. Implement the OriginatorConfidentialityLabel + AlternativeConfidentialityLabel + Classification + ClassificationCategories + Caveats + Releasability + Releasability+ Conditions XML elements per the published XML Schema Definition (XSD). Map national classification systems (US NOFORN/SECRET/TS + UK OFFICIAL-SENSITIVE/SECRET/TOP-SECRET + DE VS-NfD/GEHEIM + FR DR/CD/SD/TSD + EU RESTREINT-UE/CONFIDENTIEL-UE/SECRET-UE) into STANAG 4774 classification equivalents.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
