Browser Support

Differences Between HTML and XHTML

The xmlns attribute is required in XHTML but it is invalid in HTML.

However, the HTML validator at does not complain when the xmlns attribute is missing in an XHTML document. This is because the namespace "xmlns=" is default, and will be added to the <html> tag even If you do'nt include it.
