     I have a late comment on this document that I discovered while 
reviewing draft-ietf-netconf-nmda-netconf.  Sorry about the timing, but 
better to make the comment now rather then as an errata...

This document says:
    All NETCONF servers supporting YANG 1.1 [RFC7950] are required to
    support YANG Library (see Section 5.6.4 of RFC 7950).  NETCONF
    servers implementing the NETCONF extensions to support the NMDA
    [I-D.ietf-netconf-nmda-netconf] MUST implement at least the version
    of the YANG library defined in this document.  Similarly, all
    RESTCONF servers are required to support YANG Library (see Section 10
    of RFC 8040).  RESTCONF servers implementing the RESTCONF extensions
    to support the NMDA [I-D.ietf-netconf-nmda-restconf] MUST implement
    at least the version of the YANG library defined in this document.

I read this as an  update to RFC7950 and this should be noted in the 
document header, the abstract and Intro.
