The content of the document……
</body></html>

Differences Between HTML and XHTML
The xmlns attribute is required in XHTML, but is invalid in HTML.
However, the HTML validator at http://w3.org does not complain when the xmlns attribute is missing in an XHTML document. This is because the namespace “xmlns=http://www.w3.org/1999/xhtml” is default, and will be added to the <html> tag even if you do not include it.
| Attribute | Value | Description |
|---|---|---|
| xmlns | http://www.w3.org/1999/xhtml | Specifies the XML namespace attribute (If you need your content to conform to XHTML) |
Global Attributes
The <html> tag also supports the Global Attributes in HTML.
