Re: [i2rs] I-D Action: draft-ietf-i2rs-ephemeral-state-13.txt

Hi Sue,

Looking at requirement REQ-07, I had a further clarifying question:

3.4. Ephemeral Configuration overlapping Local Configuration

    Ephemeral-REQ-07: Ephemeral configuration state could override
    overlapping local configuration state, or vice-versa.
    Implementations MUST provide a mechanism to choose which takes
    precedence.  This mechanism MUST include local configuration (policy)
    and MAY be provided via the I2RS protocol mechanisms.

It is unclear to me whether this requirement only covers the specific 
case that a datanode for the same YANG schema leaf exists with two 
different values in both the local configuration and ephemeral 
configuration datastores, or whether it is also necessary to allow one 
datastore to override the other datastore by deleting a datanode for the 
same YANG schema leaf.

E.g. if ephemeral ds overrides local configuration ds, and the local 
config ds has leaf foo=true, and ephemeral wants to override and force 
leaf foo to be deleted altogether.

Thanks,
Rob
