 *   <li>Constructor passing required fields.
 *   <li>Constructor that will instantiate the object from an appropriate XML
 *       DOM element.
 *   <li>Get/set methods for each attribute that this element can contain.
 *   <li>A get/setVector method is provided for sets of attributes.
 *   <li>SaveToXML method. Serializes this class within a passed in element.
