Re: [core] CBOR Encoding of Data Modeled with YANG

[Juergen Schoenwaelder <[e-mail]>]

Hi,

can you configure you mail client to produce traditional quotings?

Concerning your questions, I suggest you use the terminology of RFC
6020bis wherever possible. Concerning the data node ids, I am clueless
how those numeric IDs will be managed since this has been left
out. YANG provides names. Additional numeric assignments do not
scale. Anyway, the way things are named should be part of the document
since otherwise things are incomplete.
