Template talk:Document markup languages

XML
Is XML missing from this list? 24.8.100.21 (talk)

JSON?
Does JSON really belong on this list? I think it might be better classified as a data markup language like XML (in the general). If no one has any objection, I'll pull it from the template and pull the template from the JSON page. — Preceding unsigned comment added by Mount Flatten (talk • contribs) 06:07, 7 May 2013 (UTC)
