Type: Technical
Reported by: Jan Lindblad <[e-mail]>

Section: 3

Original Text
-------------
  augment "/nw:networks/nw:network/nw:node/tet:te"
        + "/tet:te-node-attributes" {
    when '/nw:networks/nw:network/nw:network-types'
       + '/tet:te-topology/wsont:wson-topology' {
      description
        "Augmentation parameters apply only for networks with
         WSON topology type.";
    }


Corrected Text
--------------
  augment "/nw:networks/nw:network/nw:node/tet:te"
        + "/tet:te-node-attributes" {
    when '../../../nw:network-types/tet:te-topology/'
       + 'wsont:wson-topology' {
      description
        "Augmentation parameters apply only for networks with
         WSON topology type.";
    }


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 wsont:wson-topology. 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 wsont:wson-topology type. There are also other ways to fix this issue.
