The document at http://www.w3.org/TR/xhtml1/ states in section 3.1.1
"Strictly Conforming Documents" must (1) the document must conform to the
in the case of the DCMI site this is true except HTML Tidy reports
accessibility problems. (2) the root element of the document must be "html",
if it weren't "html" it wouldn't pass rule (1).  (3) the root element of
the document must contain an xmlns declaration with the namespace
"http://www.w3.org/1999/xhtml", in the case of the DCMI site it fails to
do this. (4) and (5) are non-issues as the DCMI site does those as well.

Thus, the DCMI Web pages essentially use the "nil" namespace rather than
the default xmlns= namespace.
