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

You may review the report below and at:

Type: Technical
Reported by: Ebben Aries <exa@arrcus.com>

Section: 14

Original Text
deviate-delete-stmt = deviate-keyword sep delete-keyword-str optsep
                      (";" /
                       "{" stmtsep
                           ;; these stmts can appear in any order
                       "}") stmtsep

Corrected Text
deviate-delete-stmt = deviate-keyword sep delete-keyword-str optsep
                      (";" /
                       "{" stmtsep
                           ;; these stmts can appear in any order
                       "}") stmtsep

Section specifies all permitted substatements for the "deviate" statement however the ABNF grammar specifies different valid substatements per deviate argument.  The "delete" argument is one such that only contains a subset of what is defined in the substatement table in this section.

The errata mentioned at: https://www.rfc-editor.org/errata/eid5489 is meant to correct the following statement

The argument "delete" deletes properties from the target node.  The
properties to delete are identified by substatements to the "delete"

However this either needs to be a per argument table or ABNF correction

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.
