The Variants and Actions menus contain <ul> and </ul> tags without any content, which causes all Wikipedia pages to fail the validation service provided by the W3C. An example can be found here: http://validator.w3.org/check?uri=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMain_Page&charset=%28detect+automatically%29&doctype=Inline&ss=1&group=1&verbose=1&user-agent=W3C_Validator%2F1.2
