   changes due to the differences between XML and SGML.

  Relationship values can be used in principle:

   a) for document specific toolbars/menus when used

      with the link element in document head e.g.

        start, contents, previous, next, index, end, help

   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="alternate" media="print")

  can also be expressed as attribute/value pairs on the

  param is used to supply a named property value.

  In XML it would seem natural to follow RDF and support an

  abbreviated syntax where the param elements are replaced

  by attribute value pairs on the object start tag.

   To avoid accessibility problems for people who aren't

   able to see the image, you should provide a text

   description using the alt and longdesc attributes.

   In addition, avoid the use of server-side image maps.

   Note that in this DTD there is no name attribute. That

   is only available in the transitional and frameset DTD.

 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 rules attribute defines which rules to draw between cells:

 If rules is absent then assume:

     "none" if border is absent or border="0" otherwise "all"
