This does not occur on validator.nu, and according to the list of named character references (http://www.w3.org/TR/html5/named-character-references.html), this is still valid. 64626 1 mike 2012-02-26 19:30:57 +0000 If you're seeing the message "reference to undeclared general entity hellip", it's because your document is being parsed as "XML; don't load external entities" instead of HTML. So you may need to manually set the validator to one of the HTML5 presets (instead of the XHTML5 ones). I don't know why you'd be seeing different behavior between the W3C Nu Validator and the validator.nu, but if you can point me to a URL I can check with, I'll do that.
