I would like to see such a capability as well.  As mentioned, specifically when 
groupings are used in multiple places, augmentation becomes really unwieldy 
without an option to simply augment the grouping instead.  It also gets harder 
to read; to some degree it negates the benefits from ntroducing groupings in 
the first place.

Subject: [netmod] Augmentation to Groupings


During the discussions of TE tunnel and topology models, we have found that it 
is desirable to have the capability of augmenting a grouping.

In our case, there are multiple technology specific models augmenting a base 
generic model. In the base model, some groupings are used multiple times, and 
each augmentation model needs to add more schema nodes to the grouping 
structure. For now, we have to specify an “augment” statement for each location 
where the grouping is used. Such an “augment” statement is repeated many times. 
It would be convenient and cleaner if we could augment the grouping.

We’d like to hear opinions on the feasibility of such a capability.

Thanks,
