Yes. And then you end up with a domain-model that is badly designed because XML is not capable of expressing rich and nice-to-use data structures (as is possible both in OOP and in FP languages). You end up with lowest-common-denominator stuff, at which point you might just as well use JSON and parse it into something type-safe yourself (or not, and just use it as a [String: Any] dict).
