https://en.wikipedia.org/wiki/Billion_laughs_attack https://en.wikipedia.org/wiki/Billion_laughs_attack https://en.wikipedia.org/wiki/XML_external_entity_attack https://en.wikipedia.org/wiki/XML_external_entity_attack XML is so much more than hierarchical data serialization format. In a typical conversation XML generally means "JSON-compatible subset of XML" as if the other parts do not even exist. Like in the meme "Javascript vs Javascript the good parts". XML never really took off, only the parts that make up "different flavor of JSON".
