Hi Vijay, all,

Thank you for your review.  

The nits can be addressed, presumably by the RFC editor (unless more are found).  

As for your “minor” point: Clearly, a normative document can contain informative material.  Compared to certain other SDOs, IETF RFCs commonly contain a lot of explanatory text, examples and such, which is most often purely informative.  If such text were collected in distinct sections, I believe it is a good (and unfortunately underutilized) idea to label those sections as informative.  We have done so in the past, for example in the RTP payload format for H.264/SVC, which is referenced by the subject draft (see section 13 of https://tools.ietf.org/html/rfc6184).  It’s also common practice in ITU and ISO/IEC/MPEG media coding standard documents, and implementers of the subject draft are likely familiar with those media coding documents.  Insofar, my preference would be to leave that headline as is.  However, that preference is a weak one, and if others suggest removal of the word “informative”, we could certainly do so with minimal effort.

Regards,
Stephan
