[netmod] Datastore metadata: Re: New Version Notification for draft-lengyel-netmod-yang-instance-data-00.txt

[Balazs Lengyel <[e-mail]>]

Hello Jurgen,
OK, I will add some text about:

datastore selection, default being running/operational for config 
true/false data, mentioning NMDA.

I will add a ida:datastore metadata that can placed on any any data-node (?)

A section about a use case of having examples in documents

regards Balazs
