I recently experimented with subflow possibilities and how far the core nodes can bring you. Pretty far it turns out. As I found the result quite useful I also published the flow on the Flows library. Unfortunately not all nodes are recognized as core Node Type. Of course not a big thing, normally not an issue at all, just this time had my goal set to stick on the core track. Maybe a known issue with the library code, or perhaps I have messed with somthing?
The flow is tagged with opcxml
