Hello again Benjamin:

I published -15 https://www.ietf.org/rfcdiff?url2=draft-ietf-6lo-minimal-fragment-15 with the changes.
I kept the Datagram_Tag uppercased but we can debate that with the RFC editor. 
The lowercase is used in RFC 4944.

Looking at the diffs, I found that I forgot to remove the old version of the text you changed, it is now removed in github.

Again, a great many thanks!!

I guess we're done with both fragment drafts : )

Keep safe,

Pascal

I changed the intro to add " of the datagram" to define it more clearly in the first use:
 "
The routing decision is made on the first
   fragment of the datagram,

" 
and checked it is aligned the use of "first fragment" throughout.

The particular sentence you point out could become
"
The length of the packet is indicated in each fragment (the Datagram_Size field), so node B can allocate the buffer even if the fragment it receives first is not the first fragment.
"
