If you want tagged data, why not just pick a representation that does that?

Because (imo) the goal should be to minimize overall complexity.
Pulling in XML and all of its additional complexity just to get a (debatably) cleaner way to express tagged unions doesn’t seem like a great tradeoff.
I also don’t buy the degenerate argument. XML is arguably worse here since you have to decide between attributes, child nodes, and text content for every piece of data.
