Attributes

This element includes the global attributes.

manifest
Specifies the URI of a resource manifest indicating resources that should be cached locally. See Using the application cache for details.
version
Specifies the version of the HTML Document Type Definition that governs the current document. This attribute is not needed, because it is redundant with the version information in the document type declaration.
xmlns 
Specifies the XML Namespace of the document. Default value is "http://www.w3.org/1999/xhtml". This is required in documents parsed with XML parsers, and optional in text/html documents.

Example

<!DOCTYPE html>
<html>
  <head>...</head>
  <body>...</body>
</html>
