Hello Charlie

Moving the vendor IE section to appendix would work for me just fine, but then 
I'd expect a sentence in the IANA section that explains that there is no 
reservation for vendors subtypes, rationale being in appendix or something. The 
move is more important if the doc stays standard track, but I do not see a good 
reason for that.

Note also that things can be required by an RFC without the RFC 2119 imperative 
(uppercase) form. That form is a clarification.

Take care,

Pascal

Hello Pascal,

I hope that the ADs can advise about the level of review required for 
additional assignments.  Your suggestion for RFC required is also reasonable, I 
think, given that the IETF is owning the assignment.  I observe that "RFC 
required" is about the same as "MUST be supported by an RFC", which means to me 
that the word "required" also carries with it the meaning specified by 2119.  
But anyway I am happy to go along with whatever people decide about this.  I 
doubt that there is much room for misinterpretation one way or the other.

What do you think about my suggestion to put the "Vendor IE" section into the 
appendix?

Regards,
Charlie P.

Dear all :

I am an assigned INT directorate reviewer for 
https://tools.ietf.org/html/draft-kivinen-802-15-ie-02. 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 http://www.ietf.org/iesg/directorate.html.

Document: draft-kivinen-802-15-ie
IEEE 802.15.4 Information Element for IETF
Reviewer: Pascal Thubert
Review Date: October 13, 2016
IETF Last Call Date: TBD

Summary:

Tero's draft was developed outside of the working group but is an enabler for 
solutions developed at 6lo and 6TiSCH. This review comes after the ones by Pat 
and then Charlie, who provided the adequate comments regarding IEEE802.15.4 and 
ANA. This review abstains to comment on that. Also, this review is made in the 
light of the Charlie's proposed update.

Major issues:

I am not sure that "expert review" is the right policy for section 8 on IANA 
considerations. This registry is for IETF use only. Suggestion is to use "RFC 
required":
"
   Future assignments in this registry are to be coordinated via IANA under the 
policy of "RFC Required" (see RFC 5226).
"

Intended Status for this document: Seems to me that  informational should be 
the right level; see for instance 
https://tools.ietf.org/html/draft-ietf-6lo-ethertype-request-01
Related: In the -04 that Charlie attached, I saw that uppercase imperatives 
were added. I do not think that's a good idea:

-         Imperative "MUST" in section 7 refers to the writing of other 
documents and is probably not appropriate.

-         Imperative "SHOULD" in section 7 does not refer to the behavior of 
the implementation of this document and is probably not appropriate either.

-         If those go away, ref to RFC 2119 is not needed and the specification 
can take the informational path, much easier


Minor issues:

 The need for section 5 does not appear until the IANA section. The way it is 
done works, but leaves the reader puzzled. Swapping 5 and 6 and then one last 
sentence saying that there is no need to block subtype IDs in the IETF IE for 
Vendor Specific work would have made the reading a bit smoother.

Do we need 20% of the subtypes for experimentations? 240 to 255 seems enough to 
me...


Many thanks, Tero, for this much needed work!

Pascal
