Re: [netmod] Important: Guidelines for YANG module authors

Hi,

I am trying to complete rfc6087bis.
It has been held up waiting for this draft.
It is not clear to me how sec. 6.23 (Operational Data) needs to change.
Should the whole section be replaced by an informative reference to this
new draft?
