Well the document "<title>foo</title>bar" is valid HTML (not XHTML)
if appropriately decorated with a DOCTYPE declaration,
and means "<html><head><title>foo</title></head><body>bar</body></html>".
HTML 4.01 has four phantom elements: html, head, body, and tbody (inside
tables).

Okay, fair enough.

Okay. Required attributes have to go someplace, and EMPTY or CDATA or other
oddball contents can't just appear without any lexical labeling.
