Hi Reshad,

Thank you for your valuable feedback on the draft. I have addressed both of 
your observations and uploaded version -02 to the datatracker.

Datatracker link: 
https://datatracker.ietf.org/doc/draft-rtv-netmod-yang-subtree-replacement/

Changes in draft-rtv-netmod-yang-subtree-replacement-02:

ISSUE 1: Missing <CODE BEGINS> Markers - ADDRESSED
Your observation: "the module containing the deprecated-info extension doesn't 
have the <CODE BEGINS> marker"
Fixed:

  *   Added <CODE BEGINS> and <CODE ENDS> markers to the ietf-lifecycle-ext 
module per RFC 8407bis requirements
  *   Module filename: [email protected]
  *   The datatracker now successfully extracts the YANG module (confirmed via 
xym tool output)
  *   YANG validation is now operational and passes cleanly

ISSUE 2: Incorrect Section Structure - ADDRESSED
Your observation: "module ietf-deprecated-info is in section 5.1 which is under 
'Section 5 - Example implementation'"
Fixed:

  *   Created new normative Section 4: "YANG Module"
  *   Moved ietf-lifecycle-ext module to Section 4.1 (normative placement)
  *   Section 5: "Implementation of Lifecycle Tuples Across Various Scenarios"
  *   Section 6: "Example Implementation" (now contains only test/example 
modules)
  *   Clear separation between normative YANG module and example implementations

Additional Improvements:

  *   Added complete RFC 8407-compliant copyright boilerplate to the YANG module
  *   Added proper revision statement with reference to this draft
  *   Fixed all YANG validation warnings (pyang shows 0 warnings)
  *   Module now includes proper contact information and BCP 14 keywords notice

Validation Status:

  *   YANG module extraction: Successful
  *   pyang validation: 0 warnings (previously 2)
  *   yanglint validation: Pass
  *   idnits: 1 minor warning (non-ASCII typography, cosmetic only)

The draft is now properly structured with the normative YANG module in its own 
section, and all YANG validation checks pass successfully.

Please let me know if you have any additional feedback or concerns.

Best regards,
Rajesh

Hi Rajesh, authors,

On the datatracker page, there is no YANG validation for this document. I think 
this is because the module containing the deprecated-info extension doesn't 
have the <CODE BEGINS> marker, see 
https://www.ietf.org/archive/id/draft-ietf-netmod-rfc8407bis-28.html#name-code-components

And module ietf-deprecated-info is in section 5.1 which is under "Section 5 - 
Example implementation", I'm assuming that it's a mistake in that 5.1 is 
normative and not an example?

Regards,
Reshad.
