The HEAD section is not optional. The DTD says:
<!ELEMENT HTML O O (%html.content;) -- document root element -->
<!ENTITY % html.content "HEAD, BODY">
which means that in an HTML document, both HEAD
and BODY sections are mandatory and must appear in that order.
While the section is mandatory, the start and end tags for
HEAD are optional. This makes it difficult for browsers to
detect where the head ends and content starts.
So the spec doesn't say that the HEAD section is optional,
only the start and end tags. I hope this helps.
