<RR> And I didn't receive Michael's response to Steffen. Not in my Junk folder either.....
[stf] Michael also just received my response to your email. ANIMA WG was in cc so I’m not sure what happened.


I saw that the constraint voucher follows the same approach.
<RR> Where is the constraint voucher defined?

Maybe related to this, would it be better to augment the voucher than as requested by Reshad or the voucher-request as we currently do it. I also had a look into the constraint voucher as there are also enhancements defined. So I guess I should go with the augmented voucher?
<RR> I didn't see a voucher-request node but I'm probably looking for the wrong thing.
[stf] You answered this already with your hint in the previous email. We cant augment the yang-data is what I understood as it does not allow augmentation.


Best regards
Steffen

<RR> It doesn't. It's just usually people use the same prefix as defined in the module. No big deal if you want to use a different one, I was just curious why.

Regards,
Reshad.

I meanwhile changed it to vcr. If it has no relevance outside the module, it should not be a problem
