The following errata report has been held for document update 
for RFC8542, "A YANG Data Model for Fabric Topology in Data-Center Networks". 

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7055

--------------------------------------
Status: Held for Document Update
Type: Technical

Reported by: Jan Lindblad <jlindbla@cisco.com>
Date Reported: 2022-07-29
Held by: Alvaro Retana (IESG)

Section: 4

Original Text
-------------
augment "/nw:networks/nw:network/nw:node" {
  when '/nw:networks/nw:network/nw:network-types/'
     + 'fabric:fabric-network' {
    description
      "Augmentation parameters apply only for networks
       with fabric topology";
  }


Corrected Text
--------------
augment "/nw:networks/nw:network/nw:node" {
  when '../nw:network-types/fabric:fabric-network' {
    description
      "Augmentation parameters apply only for networks
       with fabric topology";
  }


Notes
-----
The original YANG statements make the augmentation apply to all nw:networks as soon as there is at least one nw:network that is of fabric:fabric-network topo. This is clearly not the author's intent, as proven by the text in the description statement.

The corrected YANG statements make the augmentation only apply to the specific nw:networks that are of fabric topology. There are also other ways to fix this issue.

===
[AD Note] I believe that the original intent was as shown in the corrected text.  However, the resolution is not straightforward, and an update may require further consideration in light of the current rules (rfc7950).  Therefore, I am marking this report as "Hold for Document Update" [1].
