The following errata report has been submitted for RFC7564,
"PRECIS Framework: Preparation, Enforcement, and Comparison of Internationalized Strings in Application Protocols".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=7564&eid=4568

--------------------------------------
Type: Technical
Reported by: Sam Whited <sam@samwhited.com>

Section: 3

Original Text
-------------
Preparation entails only ensuring that the characters in an
individual string are allowed by the underlying PRECIS string
class.

Corrected Text
--------------
Preparation entails applying some or none of the rules specified for a
particular string class or profile thereof to an individual string, and
ensuring that characters in the resulting string are allowed by the
underlying PRECIS string class.

Notes
-----
The original text makes it sound like preparation is ONLY validating that the characters in a string are allowed in the underlying PRECIS string class, however, some profiles (for example, see the UsernameCaseMapped profile) specify that some of the rules must be applied first (in the case of UsernameCaseMapped, preparation includes first applying the Width rule).

Instructions:

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
