Andy: 

 

I’m not sure I answered #2 – is the mandatory good enough for I2RS?  The answer is yes.

Hi,

 

I would like to simplify the draft a bit further.

 

1) module-level "ephemeral" flag

Since the data node flag applies to the entire subtree,

it should be simple enough to just require each top-level

data node to declare 'ephemeral true' if needed.

There are usually 1 - 2 top-level data nodes per module so

this is not a burden.  Checking 2 places is too complicated

and they can conflict.

 

2) groupings wrt/ edit overlap

 

YANG already has a way to say what sub-nodes must

be present (mandatory=true, min-elements>0).

Is this good enough for I2RS?  Can the requirements

for the ephemeral version be different than the

persistent version, wrt/ mandatory & min-elements?
