16  * Represents the bindingKey element within the UDDI version 2.0 schema.
17  * This class contains the following types of methods:
18  *
19  * <ul>
20  * <li>A constructor that passes the required fields.
21  * <li>A Constructor that will instantiate the object from an appropriate XML
22  * DOM element.
23  * <li>Get/set methods for each attribute that this element can contain.
24  * <li>A get/setVector method is provided for sets of attributes.
25  * <li>A SaveToXML method that serializes this class within a passed in
26  * element.
27  * </ul>
28  *
29  * Typically, this class is used to construct parameters for, or interpret
30  * responses from, methods in the UDDIProxy class.
