Hi Richard, http://www.w3.org/International/questions/qa-no-language still says: “For example, because the XHTML DTDs define xml:lang in such a way that an empty string value for the xml:lang attribute is disallowed, you can't use the empty string in XHTML. “Implications for XHTML/HTML For XHTML and HTML you should use und if you need to express the undefined nature of some text embedded in a document, because (as mentioned above) xml:lang="" is not allowed.” That was the case for HTML 4 and XHTML 1; but became irrelevant with HTML5. HTML5 (or HTML for short) explicitely allows the empty string: “[The lang attribute’s] value must be a valid BCP 47 language tag, or the empty string.” [http://www.w3.org/html/wg/drafts/html/master/dom.html#the-lang-and-xml:lang-attributes] The article should cover the current situation (i.e. HTML5) and mention the past (HTML 4 and XHTML 1) in a side note.
