Re: [CCAMP] Yangdoctors last call review of draft-ietf-ccamp-rfc9093-bis-04

["Sergio Belotti (Nokia)" <[e-mail]>]

Hi Joe,

thanks a lot for your careful review and comments.

We have updated the model following  your suggestion in most of the indicated points, where we do not follow suggestion we provided a comment on line .
You can find the YANG updated module and diff with the previous one at https://github.com/ietf-ccamp-wg/ietf-ccamp-layer0-types-ext-RFC9093-bis/pull/70

See in line for comments (marked [Belotti Sergio-Italo Busi].

Thanks
Italo and Sergio

[Belotti, Sergio-Italo Busi] : Changing to relative path is not possible because we need to point to the same network, node, ttp, transceiver through another relative path. We have moved the code with leafref and must statements to the transceiver-capabilities grouping. A similar code (with adjusted relative paths) should be added by anyone using the transceiver-mode grouping elsewhere.

[Belotti, Sergio-Italo Busi] OK we have reviewed and made the module more consistent

[Belotti, Sergio-Italo Busi] We have in fact a specific issue #40 in github for that, saying “ Add description of the changes from RFC 9093 both in the YANG revision statement as well as in Appendix A”. Thanks to remind us.


 There is also an inconsistent use of quotes around various

[Belotti, Sergio-Italo Busi] We think to have fixed inconsistencies.

[Belotti, Sergio-Italo Busi]: We have updated all the descriptions to be consistent. The only config true attribute is the tx-channel-power which in some cases it is also used as config false. We have added a MUST in the description to limit the use of empty value only when the attribute is config false.
