I do not know what 'within a config=true parent data node' means since
a config=true schema node can exist in different datastores. I assume
you mean 'a config=true data node in a configuration datastore".

Yes, it is not really defined in YANG today what an action under a
config=true schema node means (i.e., what you really act upon) but I
would rather leave it to an update of the YANG specification to
clarify this.
