I am an assigned INT directorate reviewer for . These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/. This draft looks good for me, with only a small Nit. However, I am not an IoT expert, therefore, a review from IoTDir is necessary. I also recommend a review from 6lowpan expert, particularly Pascal Thubert, if it is practise. 'ECMA-340' is defined in reference section, but not quoted in the document. Regards, Sheng
