What to do if the value already exists when inserting it into a list?

It can be rejected.

Create a new entry, if it does not exists. Update, if it already exists.

He is referring to the list below. The expected behavior here is that update to the parent and the child list.

It needs to be updated for NRCellDU, NRCellCU & GNBCUUPFunction

suggested CPS-action: Update DataNode with children (in this case a list) all children will be replaced! All unchanged data has to be provided too.

Note 1. SNSSAIList is a list contained within each element of PLMNInfo

Yes. Refer Section-3 for field mapping

Note 2. Please note this action replace all existing list element, it is NOT an add-to-element action

<Need to discuss>

Replace data node with descendants.

Will require a new method in cps core to add something to a list.

little difference can be found between the request payload and the yang model.  Yang model is the final one.

For CPS this seems like populating the whole data tree for a given model in one go. i.e. replace all existing data

Modified the YANG model to support storing a list of Slices

Replace datanode and children.
