Any one of many, many YANG modules from such as TEAS and CCAMP have dozens and
dozens of augment, some more than a 100, almost all controlled by 'when'. The
'when' are almost all performing the same test for a presence container for the
network type but because the tree is ten deep and the augments take place at
different levels and the 'when' use the relative form of the Xpath statement,
then the 'when' take many different forms and it is not obvious that they are
correct.
Is there a drawback to using the absolute form of the Xpath statement which
would then always be the same?
Thus
A YANG Data Model for Flexi-Grid Optical Networks
draft-ietf-ccamp-flexigrid-yang-11
has
when "../../../../../../nw:network-types/tet:te-topology/"
+ "flexgt:flexi-grid-topology" {
when "../../../../../nw:network-types/tet:te-topology/"
+ "flexgt:flexi-grid-topology" {
when "../../../../nw:network-types/tet:te-topology/"
+ "flexgt:flexi-grid-topology" {
which could be
when "/nw:networks/nw:network/nw:network-types"
+ "/tet:te-topology/flexgt:flexi-grid-topology" {
if I understand aright.
