Content models and ommitted tag minimization.
It would be a bad idea to declare content models and tag minimization
in the style sheet because style sheet languages come and go, and the
parsing of a document would change based on the style sheet or style
sheet language. A better idea is to a) hard code the HTML empty elements,
b) read a DTD where available, c) require XML syntax for elements that
are neither described in a DTD nor in the HTML specifications. That means
*no* minimization and empty elements that are syntactically different from
regular start tags.
