in document draft-ietf-ipcdn-subscriber-mib-12.txt you will find (in the MODULE-COMPLIANCE): OBJECT diffServDataPathStorage SYNTAX StorageType { nonVolatile(3) } DESCRIPTION "An implementation is only required to support nonvolatile storage." Do we believe this makes sense and is wise? I have my doubts. There is nothing illegal here, but it feels strange to me, no? Thanks, Bert
