It says there to use a custom DTD
  http://www.w3.org/MarkUp/DTD/html401-rdfa-1.dtd
with HTML 4.01

But the HTML 4.01 spec doesn't allow custom DTDs:

"HTML 4.01 specifies three DTDs, so authors must include one of the
following document type declarations in their documents."
 -- http://www.w3.org/TR/html4/struct/global.html#version-info


This claim that RDFa can be used in HTML 4.01 also shows up in
the test draft.
