ISO20022 has a huge namespace and can do all kinds of things. My current focus on making transaction banking namespaces more accessible (think pain.001 002 and 008) aswell as CAMT files
Great effort, thanks! I just recently had to implement camt054 for our client and others will follow, because it's becoming the new standard soon. There's definitely a whole lot more in that namespace, yes.
I accidently also stumbled across the different einvoicing types that exist. What a space to explore :)
