[Ebben Aries via Datatracker <[e-mail]>]

Reviewer: Ebben Aries
Review result: On the Right Track

1 module in this draft:
- [e-mail]

No YANG compiler errors or warnings (pyang 2.0.1, yanglint 1.1.40, confdc 6.6.3)

Module [e-mail]:
--------------------------------------------------
- Remove WG Chairs from contact information per
  https://tools.ietf.org/html/rfc8407#appendix-B
- 'ietf-interfaces' import should reference RFC8343 rather
- Must clause for start/end-label is incorrect.  Would suggest moving this
  must statement underneath the `leaf end-label` as well:

  e.g.

  leaf end-label {
      type rt-types:mpls-label;
      must '. >= ../start-label' {
          error-message
            "The end-label must be greater than or equal " +
            "to start-label";
      }
      description "Label-block end";
  }
- Use of 'state' container under '/routing/mpls/label-blocks/label-block/state'
  These nodes could sit as r/o nodes by the looks of it directly under the
  label-block list.  In addition, do these nodes need '-count' suffixes?
  Should they rather be of type `yang:counter32`?
  See: https://github.com/netmod-wg/FAQ/wiki/NMDA-Modelling-FAQ
- Is there any intention to define any surrounding features?
