All elements in the document are contained within the root element (they are said to be descendants of the root element). As the root element, html may have no ancestors (in other words, it may not be contained within any other element).
This example shows the root element from a minimal XHTML document:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" >
Because this example is an XHTML document, the html element is also used to identify the XML namespace and language for the document, as discussed next. HTML documents do not use namespaces.
