        This is an EXPERIMENTAL version of HTML (code named Cougar) that
        extends HTML 3.2 to add support for work by the HTML ERB, including
        style sheets, scripting, the object tag, internationalization and
        some extensions to forms. The frame tags will probably be added
        once we have an agreed definition for them.

           Relationship values can be used in principle:

                a) for document specific toolbars/menus when used
                   with the LINK element in document head:
                b) to link to a separate style sheet (rel=stylesheet)
                c) to make a link to a script (rel=script)
                d) by stylesheets to control how collections of
                   html nodes are rendered into printed documents
                e) to make a link to a printable version of this document
                   e.g. a postscript or pdf version (rel=print)

<!--=================== Java APPLET tag ===================================-->
<!--
  This tag is supported by all java enabled browsers. Applet resources
  (including their classes) are normally loaded relative to the document
  URL (or <BASE> element if it is defined). The CODEBASE attribute is used
  to change this default behavior. If the CODEBASE attribute is defined then
  it specifies a different location to find applet resources. The value
  can be an absolute URL or a relative URL. The absolute URL is used as is
  without modification and is not effected by the documents <BASE> element.
  When the codebase attribute is relative, then it is relative to the
  document URL (or <BASE> tag if defined). <TEXTFLOW> avoids the problems
  with SGML mixed content. It can always be omitted *except* when the APPLET
  element hasn't any content. White space, comments and PARAM elements
  don't count as content for this purpose. TEXTFLOW was introduced into
  the DTD to satisfy SGML parsers, but is ignored by current Web browsers.

<!--
 The BORDER attribute sets the thickness of the frame around the
 table. The default units are screen pixels.

 The FRAME attribute specifies which parts of the frame around
 the table should be rendered. The values are not the same as
 CALS to avoid a name clash with the VALIGN attribute.

 The value "border" is included for backwards compatibility with
 <TABLE BORDER> which yields frame=border and border=implied
 For <TABLE BORDER=1> you get border=1 and frame=implied. In this
 case, its appropriate to treat this as frame=border for backwards
 compatibility with deployed browsers.
