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

Status: Held for Document Update
Type: Technical

Reported by: Radek Krejci <[email-masked]>
Date Reported: 2020-03-27
Held by: Robert Wilton (IESG)

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
-----
The document does not specify whether the “require-instance” keyword is allowed in typedef refinements derived from the “leafref” or “instance-identifier” base types, but it is anticipated that a future revision of YANG would allow this.   It is suggested that modules using YANG language versions 1 [RFC 6020] and 1.1 [RFC 7950] avoid using this construct, YANG module validation tools flag a warning if this construct is used, but implementations allow this if possible.
