No, I'm saying that JSX isn't XML, it just very loosely resembles it. It can't even naively output XML because it (currently) mandates a single root node, and XML has a doctype node as a sibling to that.

JSX transpiles down to a tree of function calls, it's literally nothing more than that, the only time it might be considered XML is in the final rendered content. Syntactically, JSX isn't even valid XML.
