A
An XHTML5 document is the XML serialization format of an HTML5 document.
The top level structure of an XHTML5 document
consists of three parts:
- XML processing instruction - Provides XML version information and character set declaration.
- Document type declaration - Provides the document type and version information.
- Document root element - Provides the root element of the document: html. It must include the "xhtml" namespace definition.
The following tutorial sample shows you how the HTML5 document top level structure looks like:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html xmlns="http://www.w3.org/1999/xhtml"> <html> (Second level structure) </html>
