I don't think people realize just how important XML is in this space (complex documentary editing, textual criticism, scholarly full-text archives in the humanities). JSON cannot be used for the kinds of tasks to which TEI is put. It's not even an option.
Nothing could compel me to like XSLT. I admire certain elements of its design, but in practice, it just seems needlessly verbose. But I really love XPath, though.
