What we want to express is that if the NC client sends a request to configure an object of class base we have a means to express that it also has to send a value for the augmented leaf. The reason why it is in an augment is because we can't modify the base class.

It seems as if you're saying that if the client thinks that leaf d is mandatory then leaf d is mandatory. Otherwise leaf d is not mandatory. /martin > > > > Best regards - Vriendelijke groeten, > > Bart Bogaert > > Broadband-Access System Architect Data > > Contact number +32 3 2408310 (+32 477 673952) > > > > NOKIA > > Copernicuslaan 50, 2018 Antwerp, Belgium Fortis 220-0002334-42 VAT BE > 0404 621 642 Register of Legal Entities Antwerp > > > > << > This message (including any attachments) contains confidential > information intended for a specific individual and purpose, and is > protected by law.
