Subject: tool to create define_keywords

To ease writing define_keywords lines, I wrote
the following tool. (see also home.wtal.de/klaus/jed/)

define makedks_read() %                                                %{{{

   bob();
   while (andelse{ bol_fsearch( "#iffalse")}{ down(1)})

   if (not i) error("flag not found");
   
   for (i=0;i<3;i++)
     {

        while ( down(1))
          {
             skip_white(); if ( eolp()) break;
             push_mark(); skip_chars( "^ \t");
             if ( s[i] != "") s[i]+= " ";
             s[i]+= bufsubstr();
          }
     }
   return s;
}

     }
   
   return strchop( s, ' ', 0);
}

             insert( v+t[1]+"\","+t[0]+","+string(i)+");\n");

example
-------------------------------------------------------------------
private variable m= "CSS";
create_syntax_table(m);
define_syntax( "/*", "*/",        '%',m); % comment
......................
% define keywords for pre-preprocessing with makedks
()=define_keywords_n(m,"abipq",1,0);
()=define_keywords_n(m,"brdlemh1h2h3h4h5h6hroltdthtrttul",2,0);
()=define_keywords_n(m,"coldeldfndivimginskbdmapprevar",3,0);
.......................
()=define_keywords_n(m,"blockquote",10,0);
()=define_keywords_n(m,"clipfont",4,1);
......
()=define_keywords_n(m,"dashed",6,2);

#iffalse
keywords -- 0, 1 and 2, each delimited by a blank line
  body
  p
  hr
  br
  span
......................
  fieldset
  
  padding
.......................
  display
  font
  
  solid
  dashed
  none
  left
  right
  
#endif  

-------------------------------------------------------------------

Has anyone fortunately a complete list of (supported) css2 keywords?
(for syntax highlighting and maybe context-sensitive tab completion)
