I'm getting to the documents I picked up from Pete when he left the
IESG. While I await the shepherd writeup for
draft-ietf-precis-nickname, here's my AD review of it. The items
marked "DISCUSS" below are things I think we need to resolve before I
request last call. It'd be nice to sort out the others before then
too, but I won't hold things up for them.
--------
DISCUSS
-- Section 1.2 --
Many important terms used in this document are defined in
[I-D.ietf-precis-framework], [RFC6365], and [Unicode].
I think that makes 6365 a normative reference.
-- Section 3 --
The following examples illustrate strings that are not valid
nicknames because they violate the format defined above.
For this and examples 9 and 10, I'm confused. The text above does not
tell me that "foo bar" is not a valid nickname -- only that the
process of preparing it for comparison normalizes it to "foo bar" (and
similarly for " foo "). Where is it that you say that the application
of rule 2 is different from the application of other rules?
--------
COMMENT
-- Section 2.2 --
An entity that performs enforcement according to this profile MUST
prepare a string as described in the previous section and MUST also
apply the rules specified below for the Nickname profile (these rules
MUST be applied in the order shown).
Is the first part of that sentence necessary? Section 2.1 already has
MUSTs; why do we have to repeat that you MUST apply Section 2.1? I'd
just say:
NEW
An entity that performs enforcement according to this profile MUST
apply the rules specified below for the Nickname profile, in the
order shown below.
END
2. Leading and trailing whitespace (i.e., one or more instances
of the ASCII space character at the beginning or end of a
nickname) MUST be removed (e.g., "stpeter " is mapped to
"stpeter").
Most of our protocols consider HTAB to be "whitespace", but it isn't
here (CHARACTER TABULATION isn't in the Zs category). Is that OK? Is
it worth specifically mentioning that, considering how common it is?
-- Section 5 --
Why does the text for "case mapping rule" say "for comparison
purposes", while none of the others do? Nothing in the document text
makes the case mapping rule special.
