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