The following errata report has been submitted for RFC6241,
"Network Configuration Protocol (NETCONF)".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5401

--------------------------------------
Type: Technical
Reported by: Rohit R Ranade <rohitrranade@huawei.com>

Section: 8.9.1

Original Text
-------------
   The XPath expression MUST return a node set.  If it does not return a
   node set, the operation fails with an "invalid-value" error.

Corrected Text
--------------
   The XPath expression MUST return a node set.  If it does not return a
   node set, the operation fails with an <error-tag> value of 
   "invalid-value".

Notes
-----
It is unclear what is the meaning of "invalid-value" "error". Since the xpath will be part of "select" attribute, we can assume that a server can return a "bad-attribute" error-tag and having error-message indicating invalid-value for the attribute. This clarifies the <error-tag> to be used in such cases.
In other places, where error-tag has been mentioned, it is clear that "invalid-value" <error-tag> must be used.

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.
