and is of Type URI - #FIXED 'http://www.w3.org/1999/xhtml'.
It may be used on any element in the Element Index. Despite being #FIXED rather than #REQUIRED in the DTD,
the xmlns attribute is compulsory on the
html element in order for a document to pass
W3C Validation.

If present within an XHTML 1.1 document, the xmlns attribute must be set to the
XHTML namespace: "http://www.w3.org/1999/xhtml". It is mandatory on the
html element.
