19  * Represents the bindingTemplates element within the UDDI version 2.0 schema.
20  * This class contains the following types of methods:
21  *
22  * <ul>
23  * <li>Constructor passing required fields.
24  * <li>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>SaveToXML method. Serializes this class within a passed in element.
29  * </ul>
30  *
31  * Typically, this class is used to construct parameters for, or interpret
32  * responses from, methods in the UDDIProxy class.
