Comment:

"1) sec. 6.3.2:
length field in Forwarding Header covers what exactly?  it is not
really clear whether the length field counts the whole message or in
case of fragmentation only the fragment size. When reading Sec 6.7 is
seems that the former is meant, but the definition could and should be
clearer. Similarly, sec. 6.7 should be clear about this, e.g.,
describing that all Forwarding Headers are identical for fragments of
the same message with exception of the fragment field."

- Added text in 6.3.2 and 6.7, but saying the opposite.
