It&#x27;s an interesting article, but I just don&#x27;t care about these supposed advantages.  Sure, there&#x27;s XPath, but there&#x27;s also JSON Path.  As for using XML to transform XML…why not just use Lisp to transform S-expressions?<p>JSON is hardly great: rather, it&#x27;s the second-worst of the popular data interchange formats today.  XML is the worst.<p>ASN.1 isn&#x27;t really popular, which is good; I&#x27;d hate to have to decide between ASN.1 and XML.
