Andy: 

 

Two options: 

1)      Ephemeral obeys the overall configuration, 

2)      Ephemeral sets its own ephemeral limit. 

 

If you do #2, then are you suggesting we put a limit in the original data model.

I'm going to avoid answering your question to let you decide what this
functional requirement means:
Ephemeral nodes SHOULD NOT introduce their own constraints.
The presence of ephemeral nodes does not trump validation or constraints for
persistent state.

 

So if the YANG list has "max-elements 5",

and the config has 5 entries.  What happens when

5 or 10 entries are added in the ephemeral datastore?
