You are telling the validator that the document should be interpreted as
HTML 4.01 (though not using the usual doctype declaration), so it
interprets it as such, and not as XHTML. A subtle difference between SGML
(with HTML's SGML declaration) and XML means that a tag <empty/> is
terminated in XML by the '>', but in SGML by the '/', so that the '>' is
interpreted as character data, which is not permitted by the content model
for the head element.
