/**
 * Represents the overviewURL element within the UDDI version 2.0 schema.
 * This class contains the following types of methods:
 * 
 * <ul>
 *   <li>Constructor passing the 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>For sets of attributes, a get/setVector method is provided.
 *   <li>SaveToXML method. Serializes this class within a passed in element.
 * </ul>
 * 
 * Typically, this class is used to construct parameters for, or interpret
 * responses from, methods in the UDDIProxy class.
