Hi Tom, sorry about the delayed response. I think this a fair question for the WG as a whole (not me alone). My view as a WG participant is in-line below.

Should this be an augment to > networks/network/network-types/te-topology > or an augment to > networks/network/network-types > ie do you see the new technology sitting alongside te-topology or subordinate to it? IMO it depends on the specifics of the augmentation. If it is TE-specific and relying on general TE information, then subordinate makes sense to me. > wson-yang is in IETF last call and has just been revised and the presence container wson-topology is subordinate to te-topology while the description says augment network types. What matters I think is that the approach is consistent. I previously looks at this draft and it's augmentations looked correct to me. I focused more on the tree representation rather than the actual model so missed this in the description. Even so, I'm not sure I would have noticed as it reads: augment "/nw:networks/nw:network/nw:network-types" + "/tet:te-topology" { description "Augment network types to define WSON topology type."; and it's the te-topology network type (container) that is being augmented. It sounds like you'd like to see the description changed from "network types " to "te-topology network type". I think this is a fine, and very minor, clarification.
