Hi Carsten,

Okay, so thinking about converting from YANG to this CBOR representation, then would the expectation be that it is okay to use a string that represents an integer?  And is that logically the same or different?  Or would the expectation be that the zone string should be converted (normalized) to an integer if it can be?  Does any of this need to be specified?

Thanks,
Rob
