<!-- To use these, write your document like:
        <!DOCTYPE HTML [
        <!ENTITY % HTML.Optional "INCLUDE">
        <!ENTITY % html PUBLIC "-//connolly hal.com//DTD WWW HTML 1.8//EN">

        <TITLE>Here's my doc</TITLE>
        <p>It uses lots of optional features

 In practice, if you're using sgmls to validate your docs,
 you can stick the <!DOCTYPE [...]> in a separate file and
 validate with:
        sgmls -s doctype.sgml foo.html
