The lost art of XML — mmagueta (marcosmagueta.com)

There exists a peculiar amnesia in software engineering regarding XML. Mention it in most circles and you will receive knowing smiles, dismissive waves, the sort of patronizing acknowledgment reserved for technologies deemed passé. "Oh, XML," they say, as if the very syllables carry the weight of obsolescence. "We use JSON now. Much cleaner."

It can be used as alternatives. In MSBuild you can use attributes and sub elements interchangeably. Which, if you're writing it, gives you a choice of preference. I typically prefer attributes for conciseness (vertical density), but switch to subelements once the length/number becomes a (significant) downside.

Of course that's more of a human writing view. Your point about ambiguity in de-/serialization still stands at least until the interface defines expectation or behavior as a general mechanism one way or the other, or with specific schema.
