The SMIv2 does mandate a LAST-REVISION clause (see section 5 and 5.1 of RFC 2578). The IETF guidelines in addition mandate the presence of REVISION clauses and the LAST-UPDATED clause becomes redundant when you have REVISION clauses. That is why YANG only has revision statements. The YANG language itself does not mandate the presence of one or more revision statements. This is consistent with YANG's philosophy of mandating only those things that are essential for the language to function and leave other things to guidelines or applicability definitions. /js PS: If YANG were to support versioned imports, revision clauses would have to be mandatory because without version information, a compiler would not be able to resolve imports. Right now, compilers can do the right thing without having revision statements and hence they are optional. -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ NGO mailing list NGO@ietf.org https://www.ietf.org/mailman/listinfo/ngo
