Hi Kent, My thinking was along the lines of what Jurgen mentions here: there are some values in operational that come from the system, but don't come from the system DS. I don't think the intention was that *anything* marked with origin "system" is also sitting there in the system DS. My example of node "foo" having different values was between <running> and <operational> (nothing to do with system DS). In the current specs (without the new DS draft), do you agree the origin of foo would be "or:system"? I'm simply talking about a situation where the user asks for 1500 in the <running> but the server can't quite program that in the h/w due to some other constraints, or some rounding function, etc and can only do 1492 so that is what they report in <operational>. I don't think it makes sense for that leaf to suddenly now show up in the system DS.
