Specific term required. Working on a book about William Holman Hunt inspired the English student James H. Coombs to author an early analysis of systems described by this word. Brian Reid's Scribe language began a split between the procedural and descriptive types of this concept. This is the second word in the acronym of the format of a HTTPRequest object that is paired with asynchronous JavaScript to communicate with web servers. That format, in which data must adhere to a DTD to be considered valid and well-formed, has a name that prefaces this word with (*) "extensible." A lightweight example of languages described by this word was created by Aaron Swartz and John Gruber. That language, whose name is an ostensible antonym of this word, is commonly used for README files. Tim Berners-Lee created one of these languages for displaying hypertext on the web. For 10 points, what type of language for styling text documents is the "M" in HTML? ■END■
