Hi,

The cited text is in 4.4.1 (there is no 4.1.1).

I do not see any evidence that the WG intended to write the word "data-exists" but
wrote "resource-denied" instead. Therefore this cannot be changed with an errata.

The following errata report has been submitted for RFC8040,

You may review the report below and at:
https://www.rfc-editor.org/errata/eid5761

--------------------------------------
Type: Technical
Reported by: Qin WU <[e-mail]<mailto:[e-mail]>>

Section: 4.1.1

Original Text
-------------
If the data resource already exists, then the POST request MUST fail
and a "409 Conflict" status-line MUST be returned.  The error-tag
value "resource-denied" is used in this case

Corrected Text
--------------
If the data resource already exists, then the POST request MUST fail
and a "409 Conflict" status-line MUST be returned.  The error-tag
value "data-exists" is used in this case

Notes
-----
The error-tag value should be corrected as "data-exists" in this case
based on the context. According to error-tag definition in RFC6241:

   error-tag:      resource-denied
   error-type:     transport, rpc, protocol, application
   error-severity: error
   error-info:     none
   Description:    Request could not be completed because of
                   insufficient resources.

It is apparent error-tag value "data-exists" should be corresponding
to the data resource already exists condition.

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.
