I am "OK" at writing YAML but not great. If I were to express that out of 3 nodes in the DT one and only one *must* contain a certain subnode, but it doesn't matter which one, I have no idea how to express that. Since the abstract syntax in YAML is pretty much stateless this beats me. Yours, Linus Walleij
