The model you propose has the structure:

     augment /yanglib:yang-library/yanglib:module-set/yanglib:module:
       +--ro notification-sent-for-config-default?   boolean
       +--ro notification-sent-for-state-default?    boolean
       +--ro on-change-notification-capability* [data-node-selector]
          +--ro data-node-selector    nacm:node-instance-identifier
          +--ro on-change-notification-sent?            boolean

(NOTE: the tree diagram in the draft doesn't match the data model.)

So there is one "on-change-notification-capability" list per *module*
in a module-set.

This seems quite complex for a client to digest.  It is not clear how
the "data-node-selector" relates to the "module".  It probably works
fine when a module is completely self-contained with no augments, and
no other module that augements it, but it gets complicated with
augemnts.

Wouldn't it be better to have a single structure per datastore?
