When responding, please keep the subject line intact and reply to all

introductory paragraph, however.)

Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html
for more information about IESG DISCUSS and COMMENT positions.

The document, along with other ballot positions, can be found here:


** Section 3.1.  When @type=”stat” and the name of the stat is set in @name,
how does a client know the semantics of this stat?  Is that negotiated out of

** Section 4.1.  Per  <loginSec:userAgent>, how are the clients supposed to
generate the app, tech or os strings in a way that the server will understand?
If this is out of scope, please just say so.


I support Alissa Cooper’s DISCUSS position.

** Section 3.1.  Is a @value required when @type=”cipher” or
@type=”tlsProtocol”? The examples in Section 4 show the use of @value.  Also,
what format should be used to express the cipher or tlsProtocol?

** Section 3.1.  Per the description of event@lang, please cite the language
format as coming from Section 3.4.3[W3C.REC-xmlschema-2-20041028]

** Section 4.1.  Per the children of <loginSec:userAgent>, would supporting a
more formal approach also be useful -- using SWID (ISO/IEC 19770-2:2015) or
COSWID (draft-ietf-sacm-coswid)?

** Section 4.1. Per pw and newPW’s descriptions of “all internal continuous
whitepaces … is replaced with a single #x20” – is this intentionally precluding
a password with a double space?

** Section 4.1. Per “If non-ASCII characters are supported with the plain text
password, then use a standard for passwords with international characters, such
as the OpaqueString PRECIS profile in [RFC8265].”, if non-ASCII characters are
supported, how does a client know which approach to take with a given server in
an interoperable.  RFC8265 is a helpful reference but the current text seems to
provide no guidance.

** Section 5.  Please note in the Section 5 introduction that the blob between
the BEGIN and END tags in Section 5.1 are formally specified by XML Schema.

** Section 8.  Please note that the Security Considerations of RFC5730 apply
and that this document enhances these security services.

** Editorial Nits
