19  * Represents the find_binding element within the UDDI version 2.0 schema.
20  * This class contains the following types of methods:
21  *
22  * <ul>
23  * <li>A constructor that passes the required fields.
24  * <li>A Constructor that will instantiate the object from an appropriate XML
25  * DOM element.
26  * <li>Get/set methods for each attribute that this element can contain.
27  * <li>A get/setVector method is provided for sets of attributes.
28  * <li>A SaveToXML method that serializes this class within a passed in
29  * element.
30  * </ul>
31  *
32  * Typically, this class is used to construct parameters for, or interpret
33  * responses from, methods in the UDDIProxy class.
