16  * Represents the accessPoint element within the UDDI version 2.0 schema.
17  * This class contains the following types of methods:
18  *
19  * <ul>
20  * <li>Constructor passing required fields.
21  * <li>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>SaveToXML method. Serializes this class within a passed in element. *
26  * </ul>
27  *
28  * Typically this class is used to construct parameters for, or interpret
29  * responses from, methods in the UDDIProxy class.
