 * Hierbei unterscheiden wir vier verschiedene Arten von Attributen:<br>
 * <ul>
 * <li>FIX: Definierte Attribute Fix, fuer jedes Attribut ist definiert ob es required ist oder nicht (gleich wie JSP). </li>
 * <li>DYNAMIC: Die Attribute des Tag sind frei, keine Namen sind vorgegeben.
 * Es kann aber definiert sein wieviele Attribute maximal und minimal verwendetet werden duerfen.</li>
 * <li>FULLDYNAMIC: Gleich wie DYNAMIC, jedoch kann der Name des Attribut auch ein dynamischer Wert sein (wie bei cfset).</li>
 * <li>NONAME: Ein Tag welches nur ein Attribut besitzt ohne Name, sondern einfach nur mit einem Attribut Wert</li>
