Hi -

This also works for me, but I'd replace the odd "MAY" with the word "need".

(The semantics of "only" and of "MAY" don't quite mesh.)

Ah! Re-reading it I think that you are correct. In this spirit I propose the 
change shown below. I believe that all this does is (a) generalise, and (b) 
clarify. I don’t believe that it changes the intended meaning.

OLD:

It is acceptable to reuse the same revision statement within unpublished 
versions (i.e., Internet-Drafts), but the revision date MUST be updated to a 
higher value each time the Internet-Draft is re-posted.

NEW:

It is acceptable to reuse the same revision statement within unpublished 
versions (e.g., Internet-Drafts), but the revision date (i.e., the revision 
statement’s argument) MUST be updated to a higher value each time a new version 
(e.g., of the Internet-Draft) is posted.
It seems strange to talk about reusing the revision statement and, in the same 
sentence, require to change its argument. What about this:

NEW

It is not required to keep the revision history of unpublished versions (e.g., 
Internet-Drafts). That is, within a sequence of unpublished versions, only the 
most recent revision MAY be recorded in the module or submodule. However, the 
revision date of the most recent revision MUST be updated to a higher value 
each time a new version (e.g., of the Internet-Draft) is posted.

Hi -

I read the text as intended to make a distinction between the *date* portion 
and the rest

of the revision statement.  When a module is under development, retaining a 
history

of specific incremental changes isn't terribly helpful, but changing the date 
is essential

to helping tools decide among the versions floating around in the lab.

Thanks. e.g rather than i.e sounds good, BUT my point (sorry if that wasn’t 
clear) is that this sentence seems to be contradictory. It says:

1. Unpublished versions, i.e IDs, can reuse revision statements.
2. IDs MUST update their revision dates each time they are re-posted.

My suggestion of removing the parenthesised text was to remove this 
contradiction. Right now I’m not clear that I can rely on revision dates in 
YANG modules contained within IDs.

PS, I think that the removal of this text removes the contradiction because in 
order to make sense of the sentence the reader will be forced to the conclusion 
that IDs are not regarded as being “unpublished”.

Hi -

The situation with Internet-Drafts is what motivated this text in the first 
place, so
I think it is important to retain that information.  However, it seems to me 
that
the "i.e." is too limiting, and should be replaced with an "e.g.".

All,

The text at the bottom of RFC 6087bis (draft 07) Section 5.8 seems unclear:

"It is acceptable to reuse the same revision statement within unpublished 
versions (i.e., Internet-Drafts), but the revision date MUST be updated to a higher 
value each time the Internet-Draft is re-posted”

Assuming that the intent is that the revision statements in YANG models contained 
within IDs must be updated whenever the models are updated,  wouldn’t it be clearer 
if the parenthesised text "(i.e., Internet-Drafts)” was deleted?

Thanks,
William
