The HTML, HEAD and BODY tags are supposed to be optional; the browser is supposed to infer their presence from the contained material and to do the right thing. This page begins with just the DOCTYPE immediately followed by the top navigation table, that is, body material. It should look perfectly normal except for not having a TITLE element and thus no titlebar content.
The address element specially formats the mail address (in <A
mailto=>) or home page (in <A href=>) of the author of a document. It
is inline, though normally used in a block by itself. Here's the example out
of the HTML spec, slightly edited (after a BR):

In addition to not having any head material, this document has neither </BODY> nor </HTML>.
