the HEAD _element_ is not optional it has to be there.
The DTD says the content model for HTML is:
<!ENTITY % html.content "HEAD, BODY">
However because it _must_ be there, the system can tell it's there
without you needing to put any tags in, so both the start and end tag
may be omitted.
Wow. Isn't it amazing how easy the SGML world is forgotten!
And that's a bad thing?
When I started messing with markup in 1993-94, I was using HTML (pre-2.0) to
provide enhanced versions of Gopher menus for Mosaic users. I started using
both XML and XSL in 1999, like many of the other 'old-timers' on this list. I
doubt I'm in the minority here when I say I've never had any significant
exposure to SGML -- and from what I've seen of SGML, I'm quite content with my
ignorance! :)
Besides, isn't it one of the (perhaps post-facto) points of HTML and
especially XML to simplify SGML a bit, thereby enabling its widespread
adoption by people like me, who find the idea of using or producing tools for
processing SGML daunting enough to make them avoid SGML altogether?
