This document describes a YANG data model for the SCHC (Static Context Header Compression) compression and fragmentation rules. The bulk of the document is the YANG module, which I did not review as I am not a YANG expert. The rest of the document was fine and mostly consisted of conventions for what appears in the YANG module. The security considerations seemed sufficient. One minor nit, in the last sentence of security considerations, the phrase "including access right and identities" doesn't seem quite right. Maybe "including access controls and identities"?
