Summary: Ready with Nits

1: The TLV formats in the draft look identical with RFC7471 except the value in
Type field.
     it would be better to clarify this points so that the readers who are
     familiar with RFC7471 can interpret them easily. I am also wondering if
     the format figures of TLV are necessary when the same figures are already

2: There is no guidance for default values such as measurement interval in the
draft. If these values should also be inherited from other draft, it should be

3: (Editorial) The length of Type filed in the figures look 15 bits length.
