Hi Hongji,

That is fine.  Thank you for considering/discussing the options.  I have cleared my discuss.

Hi Robert,

As you summarized, each option has its pros & cons. There is no best choice.
So we plan to take the approach as Alvaro's suggestion.

Thanks a lot!

Rob:

I understand what alternate structures may have been better.  Given the stage at which we are, my preference would be to leave the model as is.

[OTOH, if the authors want to take on the work of changing the structure… I won’t be opposed — knowing what we will basically go back to square one.]

Thanks!

Alvaro.

However, this is just a preference, and I also want to see IETF YANG models completed and standardized. I.e., I will not block progression of this document if the authors & Alvaro thinks that the existing module structure is sufficient, or choose to do (2) instead.
