I am the assigned Gen-ART reviewer for this draft. For background on Gen-ART, please see the FAQ at http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq . Please resolve these comments along with any other comments you may receive. Summary: This draft is basically ready for publication, but has nits that should be fixed before publication. I originally performed a Gen-ART review on the -07 version of this draft in 2010; the comments from that review were sufficiently resolved in the -08 and -09 versions, and remain resolved in the current -12 version. I did not see anything new in the changes from -09 to -12 that requires attention. idnits 2.12.12 found a couple of things for the abstract: -- The draft header indicates that this document obsoletes RFC5504, but the abstract doesn't seem to mention this, which it should. -- The draft header indicates that this document obsoletes RFC4952, but the abstract doesn't seem to directly say this. It does mention RFC4952 though, so this could be OK. Thanks, --David ---------------------------------------------------- David L.
