Alexander,

I disagree. This YANG Library is mandatory for all implementations;
what you talk about seems to concern only implementations that support
YANG push. Hence, this is an extension that should go in its own
module.

Specifically, in the context of YANG-Push we had a discussion about being able to mark nodes that are notifiable on change.  This is just one particular use case of a more general issue; in YANG-Push after much debate the conclusion was for now to simply make implementors aware of this issue and advise that a solution to this must be provided, with the clear understanding that eventually a standard solution should be defined.

One possible way to address this would be, for a given module, to maintain a list of "meta-info", with a key "meta-tag", and a list with references to the nodes to which the metadata applies.  In the case of notifiable-on-change, you would have a list with one entry "notifiable-on-change", and then the list with the node definitions to which this tag applies.
