Tip:The file type declaration is not part of the actual content of the XHTML document. It is not an XHTML element and does not have a closing tag.

Tip:In XHTML, the xmlns attribute within the <html> tag is required. However, even if this attribute is not present in the XHTML document, the w3.org validation tool will not prompt an error. This is because, "xmlns=http://www.w3.org/1999/xhtml" is a fixed value, and this value will be added to the <html> tag even if you do not include it in the code.
