> JSX standalone is a simple syntactic transform for XML-ish notation to JavaScript

But not necessarily the same translation as in your example (that is, tags to function calls and attributes to first arguments). Perhaps all existing implementations work like that, but the spec leaves the JavaScript representation undefined. The spec draws attention to this intentional ambiguity when it lists “a set of transpilers that all conform to the JSX syntax but use different semantics on the output”.
