Thank you for noting the 'regulatory or certification requirements around this protocol' point. I need to find out.

Thanks - interface maps looks cool - I'll check in 2020.1.

I meant any classes, including plain objectscript that are called by running code, but I'd like to include dtl's and 'standard' classes for business process, etc., routing rules and schema's

I'm just used to tools that identify unused methods and classes from other IDE's and I thought maybe I missed existing functionality?
