SYNOPSIS
       namespace HTML_Tree {

	   class element;

	   class Element_Node : public HTML_Node {
	   public:
	       typedef std::map< std::string, std::string > attribute_map;

	       Element_Node(
		   char const *name, element const &elt,
		   Content_Node *parent = 0
	       );
	       Element_Node(
		   char const *name, element const &elt,
		   char const *att_begin, char const *att_end,
		   Content_Node *parent = 0
	       );
	       virtual ~Element_Node();

	       attribute_map   attributes;

	       char   const    *const name;
	   protected:
	       // overridden
	       virtual bool    similar_to() const;
	       virtual bool    write_node( std::ostream&, int, bool ) const;
	   };

       }

DESCRIPTION
       Element_Node  is-an  HTML_Node  for  HTML  elements, e.g.:
       HEAD, TITLE, IMG, SELECT, etc.

   Public Interface
       Constructors
	      Construct an Element_Node.  The arguments are:

		 name	   The name of the HTML element.  It must
			   be specified in lower case.

		 att_begin, att_end
			   Pointers  to	 the  beginning character
			   and one past the end (in STL	 iterator
			   style)  whence to parse the attributes
			   from, e.g.:

			  <IMG SRC="foo.gif" HEIGHT=30 WIDTH=200>
			      |					|
			      begin				end


		 elt	   A reference to the element  that  this
			   node is being made for.

		 parent	   The	parent	node  to make this node a
			   child of, if any.

       Destructor
	      There is nothing noteworthy about it.

       attribute_map attributes
	      Contains key/value pairs	of  attribute  names  and
	      their  values.   Attribute  names are in lower case
	      (regardless of how they  are  in	the  HTML  file).
	      Boolean  attributes  have their name as their value
	      (per the HTML 4.0 specification).

       char const *const name
	      The name of the HTML element, e.g.,  title.   Names
	      are  in  lower  case (regardless of how they are in
	      the HTML file).
