If you’re working with Joomla using an HTML5 template and you try and validate your site using the [W3C Markup Validation Service](http://validator.w3.org), you may find yourself hit with the following validation error: *Line 7, Column 44*: **Bad value title for attribute name on element meta: Keyword title is not registered.** Syntax of metadata name: A metadata name listed in the HTML specification or listed in the WHATWG wiki. You can register metadata names on the WHATWG wiki yourself.
