(11) Identify any ID nits the Document Shepherd has found in this
document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts

no nits of substance are found in draft 01
(12) Describe how the document meets any required formal review

formal review by yang doctors will be requested to coencide with IETF
(13) Have all references within this document been identified as
either normative or informative?
(14) Are there normative references to documents that are not ready for
advancement or are otherwise in an unclear state? If such normative
references exist, what is the plan for their completion?
ietf-netmod-revised-datastores is being advanced and will shortly arrive

(15) Are there downward normative references references (see RFC 3967)?
If so, list these downward references to support the Area Director in
the Last Call procedure.
There are no notable downrefs.
(16) Will publication of this document change the status of any
