Looking at it from an editorial point of view, there are a significant number of defects which make it 'Not Ready'.

IANA Considerations MUST be present as per YANG Guidelines, RFC8407; no registration, no YANG module

Security Considerations MUST follow the template as per YANG Guidelines

Examples MUST use the addresses reserved for IETF documentation, not those allocated to other organisations.

Requirements Language is out of date - see RFC8174

YANG revision statement must refer to the title i.e. 'RFC XXXX; Determistic Networking (DetNet) YANG Model'

The Information Model is now an RFC

It is unfortunate that RFC9016 is Informationsl - it needs to be a Normative Reference IMO; your AD is probably familiar with this problem as it occurred as recently as last month and will doubtless occur many times again

import yang-types references an obsolete RFC

YANG prefix is cumbersome - I think 'detnet' quite long enough and likely too long - it is a shame that dtn is in use elsewhere

references in the YANG module, RFC, IEEE or ietf-draft etc.,  MUST appear in I-D References and there needs to be a good reason why they are not Normative; I rarely see such a reason.

six authors, one for the AD to reflect on

(perhaps not a coincidence:-)

I plan to look at the technical content of the YANG which may, or may not, throw up similar a number of considerations.
