Changes in the November 15 Revision
====================================
o Added one-line comment for each element and attribute in the DTD.
Removed some other comments
o ALT is no longer required in level 0: some images are completely inessential.
o Changed DL content model to (DT | DD)+
o ADDRESS content model is always (%text|P)*
o FORM ACTION attribute is #IMPLIED (defaults to address of document)
o Removed remaining references to World-Wide Web
The one-line comments follow a pattern, so you can extract them
automatically for use in quick references and such:
