HTTP Binding Data-Binary

Oooof, all items created and values showing up. Still have to do some polishing (icons, description etc) but I’m going to open a seperate topic for that: Working with values, substracting and checking if null

God, what a misery, once it works, it works forever but the whole rule syntax and the VSCode extension lacks so much useability… cc: @Kai @rlkoshak
