You question made me look up the answer because I didn't know. I found that it is a more strict form of HTML. HTML often works without closing tags and other poor practices. XHTML does not allow those practices. From what I can tell it has not been depreciated, but the advantages have been largely done away with with HTML5. It started with HTML4 I think.
