Geez, I fixed that and have another error.
I can create the elements I need but I also need to remove elements. I
need to remove the attribute node-agent-ref from the server element and
I need to remove the node-agents elements. How do I remove the
node-agents-ref attribute? I tried setting it to null and got an
error. Also how do I remove the node-agents element?

In my case, I need to create elements (nodes and node) based on information that is in the node-agents and node-agent elements in v2. I then need to remove the node-agents references from the config. I tried to create a nodes elements but get the stace trace below.
