Re: [netmod] NULL value for uint16

The RFC editor is not going to fix this, for them it is beyond editorial. For me it makes sense to report this, let alone to spread the word that there is no NULL in YANG land. Sure, things like this should be catched earlier but things are as they are and a late fix is still better than

Re: [netmod] NULL value for uint16

I guess the description should be worded as "This leaf does not exist if ..." instead of talking about NULL, a concept that does not exist in the YANG language and the protocols. One subtle point with the "does not exist" approach is that a client cannot reliably distinguish between 'a leaf

[netmod] NULL value for uint16

Does NULL have any meaning for a leaf of type uint16? Looking at a leaf of type uint16 the description says that 'This metric will be NULL (no value) ..' Some languages differentiate a 'never been set' state from e.g set to zero or some other value but for me, YANG does not have that concept.
