								    This is the HTML 4.0 Frameset DTD, which should be				    used for documents with frames. This DTD is identical				    to the HTML 4.0 Transitional DTD except for the				    content model of the "HTML" element: in frameset 				    documents, the "FRAMESET" element replaces the "BODY" 				    element.
