 [Mail-Fmt].

This is not specific as to where the In-Reply-To header is.  I assume
you want to say that it is a header of the parent multipart component
of "Reaction" part.  Or perhaps this should be forward-referenced to
the discussion in section 3.


I don't understand the concern.  An In-Reply-To header field is part of
the message header.  That is, it will be in the header of the response
message.


Given that we're deailing with multipart messages, an In-Reply-To header
could be stuck in the message header but it could also be stuck in the
headers of any part.  I don't know if it's ever done, but certainly,
it's plausible that if I include a reply which I had received as an
attachment to another email I send, the In-Reply-To header in the
received e-mail would show up as a header to the attachment part, not
my message as a whole.

In general, the situation is one of unlimited complexity.


RFC 5322's definition of the In-Reply-To field has it being optionally 
present in the message header:


  message =  fields *( CRLF *text )   ; Everything after
 ;  first null line
 ;  is message body

 fields  =dates  ; Creation time,
  source ;  author id & one
1*destination;  address required
 *optional-field ;  others optional


 optional-field =
 /  "In-Reply-To"   ":"  *(phrase / msg-id)


As such, it's location is not as random or varied as you seem to think. 
 Also note that the In-Reply-To field has long history and is already 
well-integrated into MUAs.


So, the complexity is quite limited.

My guess is that you are confusing the variable venues possible for the 
emoji-sequence with the far less variable venue of In-Reply-To.


I suppose a clarification could be added along the lines of:

OLD:
   The emoji(s) express a recipient's summary reaction to the specific
   message referenced by the accompanying In-Reply-To header field.
   [Mail-Fmt].

NEW:
   The emoji(s) express a recipient's summary reaction to the specific
   message referenced by the accompanying In-Reply-To header field, for
   the message in which they both are present. [Mail-Fmt].

If a message is nested within a message, that defines a hard reference 
boundary.  Something inside the nested message does not refer to the 
containing message, for example.




I'm not particular what rules you want to specify, just that when I'm
looking at a part with this Content-Disposition that is somewhere in a
multipart structure (possibly without parts), that it's clear which sets
of headers I need to examine to find the In-Reply-Header.


Perhaps you could offer an example or two of messages that you see as 
creating ambiguity or other confusion?




Now I think in reality, it either has to be in the headers of the part
with disposition "reaction", or in the multipart containing that part.
But whatever the rule is, it should be stated.


see above?



 Reference to unallocated code points SHOULD NOT be treated as an
 error; associated bytes SHOULD be processed using the system default
 method for denoting an unallocated or undisplayable code point.

Code points that do not have the requisite attributes to qualify as
part of an emoji_sequence should also not be treated as an error,
although you probably want to allow the system to alternatively
display them normally (rather than as an unallocated or undisplayable
code point).


I think your comment addresses a different issue than the cited text is
meant for, but I also might be misunderstanding.

For whatever reasons, including not having been allocated by the Unicode
folks, or possibly by running an older system that thinks a code point
is not allocated, there is an issue of how the system should deal with
encountering such a code point.  The text here is merely trying to say
"do whatever you do".


The text is a constraint, though.  It *requires* (sort of) that if the
bytes in the part form a character which the receiver considers
unallocated, it *should not* reject the whole message as being
ill-formed.  The implementation has great freedom in how to display the
caracter, but the message as a whole "SHOULD NOT be treated as an
error".


Since this specification pertains to processing of some octets, rather 
than having anything to do with overall processing of the message, I am 
not understanding your concern.

To the extent that your intent is to say that a) this is a subset of

In fact, I had added the one or more text mostly to highlight the the
'sequence' can be only one byte, since 'sequence' would be expected to
be read as meaning multiple.


One small change here which will reduce the amount of confusion is to
avoid the word "byte".  Indeed, it is *not* possible for the sequence
to be only one byte, since there are no Unicode code points in the
range U+ U+007F with the Emoji property set.

So, use "emoji characters" or "code points" instead?

(I tend to avoid the use of "byte" in favour of "octet" to forestall
complaints from the old DEC-10, DEC-20 and Cray users anyway ☺)


Well, indeed, my entrenched use of byte probably gets in the way, here...

I want the term to be more low-level and physical, than abstract or 
conceptual.  That is, I'd like the term to be outside of the Unicode 
specialized terminology.  To that end, I think octet works well.

Probably, but I think it bears saying something about how to handle
code points without the Emoji property set.  IMHO they should be
handled as undisplayable.


This steps into user interface design, more than interoperable emoji 
labeling and transport.


As such, it's outside of this specification and outside of the IETF's 
expertise.

Interesting. Just discovered that this probably qualifies as a bug in

Here's the xml for that paragraph:

Sam,

Consider the level of activity on this topic that is already happening

suggest that that's the most important demonstration of organizational

The document in question marks that commitment, but it needs to be 
careful not to mark it beyond our current capabilities.


In particular please point me/us to established consensus documents that 
define the problem space, the solution space and the architectural 
choices appropriate to this topic.  I'm not aware of any, but perhaps I 
missed them.


Absent established documents on this topic, justifying is only 
reasonable in terms of demonstrating thoughtfulness, not demonstrating 
that the choices are correct.  Yet a term like justify encourages 
this latter expectations.   the view that we have far more community

[Gen-art] Consideration vs. Blocking (was Re: Gen-Art telechat review of draft-farrell-perpass-attack-04)

2014-01-19 Thread Dave Crocker

On 1/19/2014 12:30 AM, Eliot Lear wrote:

It is fair to say that we should consider this threat at an
architectural level.  It's fair (albeit a truism) that finding design
flaws earlier in the process rather than later is less costly
(ENG-101).  Justification language like the above, however, is likely to
actively impede the IETF, as these sorts of things have in the past.



If I'm understanding this exchange, it hinges on the distinction between 
due consideration vs. appropriate design response.


Pressing to have work consider an issue early and thoughtfully makes 
sense for any topic that is as important as pervasive monitoring. 
Having IESG evaluation produce a blocking Discuss because an AD feels 
that the consideration was not sufficient or the resulting design flawed 
in terms of this issue is another matter.


The point I'm seeing Eliot make is that we don't have enough community 
understanding of the topic to be sure what constitutes appropriate 
design consideration.  So, in the face of such minimal community 
understanding, an AD's blocking progress would be whimsical at best.


Based on how new this topic is -- we don't even yet have stable and 
shared terminology for the problem space nor the solution space -- 
Eliot's concern isn't just valid, it's important.


We /do/ have a long track record of well-intentioned ADs asserting 
Discusses that are reasonable in the abstract but impractical for work 
in the IETF, especially when the topic is frankly still vague.


While the formal status of this document is relevant to the concern, the 
more important issue I see is our community sense that work going 
forward needs serious effort, but also an understanding that the basis 
for blocking specification needs to be extremely cautiously applied.


By way of trying to be practical about being practical, I'll suggest 
that any IESG blocks based on a concern about pervasive monitoring needs 
to reflect a consensus view of the IESG, not just the concern of a 
single AD

2012-10-18 Thread Dave Crocker



I have wondered about that limitation for at least 15 years. I
have come up with possible explanations but without a shred of
evidence from the RFCs.



FWIW,

The construct of group is pretty much an assertion of an aggregate 
identity.  That is, an identity beyond that of the listed addressees, 
deriving from their, u... grouping.


The purpose of From: and Sender: is to assign bits of essential 
responsibility.


Unlike the current trend towards declaring personhood for corporations, 
the design motivation behind using the group construct was to restrict 
assignment of responsibilities to individuals, rather than aggregations 
of them.


All very abstract, I admit.  From the vantage point of some decades, 
even quaint.

Would a possible middle ground be to include a single

So, if the limit is still 998, then there is no change with respect the former
limit.


See the next sentence:

(Note that in
ASCII octets and characters are effectively the same but this is not
true in UTF-8.)

Remember, in UTF-8, characters can be multiple octets. So 998 UTF-8 encoded
*characters* are likely to be many more than 998 octets long. So the change is
to say that the limit is in octets, not in characters.



The switch in vocabulary is clearly subtle for readers.  (I missed it too.)

I suggest adding some language that highlights the point, possibly the same 
language as you just used to explain it.

One of the joys of the diversity of the IETF is the diversity of writing 
conventions we tolerate.  For the current document, I'm surprised we didn't wind 
up with some British spellings...


In any event, it turns out that both forms of the word are valid spellings.



  - Authors' Addresses page 78: please consider to add the zip code to
   all addresses in the USA?


Yes, that would be more considerate to provide.

Spencer, thanks.

Just for completeness, given the meta-issues that have arisen and that it is out 
of scope for your review, can you summarize the nature of what was *in* scope?
