Per WP:LISTPURP and WP:SAL, lists need to have some kind of clear selection criteria. This doesn't. It's a vague and incomplete list of standards related to web services broadly construed. This information is better portrayed simply by reading the article on web services.
In addition, it's arguable whether or not these things even count as 'markup languages' given they are rarely used for marking up text in the way HTML or Markdown or wiki syntax is (certainly something like REST isn't a markup language), but instead are basically specifications, in which case it duplicates List of web service specifications. —Tom Morris (talk) 16:51, 19 August 2012 (UTC)[reply]
