Thanks for your feedback. I realize I should have elaborated the example a bit more, it's too vague. So, as I wrote in some other reply as well, please don't over-interpret it. The point was only to say that in order to differentiate the events, we don't necessarily need distinct types (which would result in multiple schemas on a topic), but can instead encode it in one type/schema. Like mapping in ORM - instead of "table per subclass", you can use "table per class hierarchy".
