It's a pleasure! To be clear, I meant that you could have a repository that contains all of the information in some sort of configuration language (or maybe in Typescript; I suppose that doesn't really matter) but you use that to generate multiple libraries; one for each language you might want to support. So a single codebase (or configuration base) could generate iso20022.js, iso20022.ts, iso20022.py, etc etc. It's not simple; it might just be an interesting distant goal to keep in mind.
