Subject: [netmod] [Technical Errata Reported] RFC7950 (6031)

The following errata report has been submitted for RFC7950, "The YANG 1.1
Data Modeling Language".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6031

--------------------------------------
Type: Technical
Reported by: Radek Krejci <[e-mail]>

Section: 9.9.3

Original Text
-------------
The "require-instance" statement, which is a substatement to the "type"
statement, MAY be present if the type is "instance-identifier"
or "leafref".  It takes as an argument the string "true" or "false".
If this statement is not present, it defaults to "true".

Corrected Text
--------------
The "require-instance" statement, which is a substatement to the "type"
statement, MAY be present if the type is "instance-identifier", "leafref" or
a type derived from them. It takes as an argument the string "true" or
"false". If this statement is not present, it defaults to "true".

Notes
-----
As discussed in
https://mailarchive.ietf.org/arch/browse/netconf/?gbt=1&index=p_zRKwQ6TBxTuC
DPc5wJbdZgWTc, authors expect that the require-instance statement is
available not only for leafref and instance-identifier types, but also for
all the types derived from them using typedef statement. Since no one argued
against this understanding, this errata changes the text to the same form as
in other restrictions applicable to derived types.

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 can log in to change the status and
edit the report, if necessary.
